His goal is to be Earth’s virology professor. In recognition of his contribution to microbiology education, he was awarded the Peter Wildy Prize for Microbiology Education by the Society for General Microbiology, and the American Society for Microbiology Award for Education. His Wildy Lecture provides an overview of how he uses social media for science communication.
Brianne Barker, Ph.D. (TWiV) (@BioProfBarker) is Assistant Professor of Biology at Drew University. Brianne is originally from the small town of Camden, New York, where she began her love for science. She began studying immune responses to viruses as an undergraduate majoring in Biology at Duke University, studying the effect of adjuvants on antibody responses to HIV vaccine candidates in the laboratory of Barton Haynes. She received a Ph.D. in Immunology from Harvard University, studying the role of cytokines in cytotoxic T cell responses, again with an eye towards vaccine adjuvants, in the laboratory of Norman Letvin. After seeing some data on the role of the innate immune system in viral pathogenesis, Brianne joined the laboratory of Jenny Ting at the University of North Carolina at Chapel Hill for a post-doctoral fellowship examining signaling through innate immune receptors that detect microbes. She hopes that her fellow Duke basketball fans forgive this period of time spent working for the enemy. In 2013, Brianne joined the faculty at Drew University, teaching undergraduate courses in immunology, virology, microbiology, and science writing. The Barker lab studies the innate immune response to DNA and the relationship between viral pathogenesis and the evolution of DNA-sensing innate immune receptors.
Brianne is passionate about promoting women in STEM and the relationship between science and other parts of the liberal arts. She is excited to be a part of TWiV so that she can communicate her passion about science to a diverse audience. She can be found online at bbarkerdrew.com.
Kevin Bonham, Ph.D. (Audiommunity) received his Ph.D. in immunology from Harvard University studying how the cells of the innate immune system detect and respond to the presence of infectious microorganisms. He is now a curriculum fellow for the Masters program in immunology at Harvard. You can find him all over the web (food blog, other blog,twitter, reddit).
Rich Condit, Ph.D. (TWiV) began his scientific career at the age of six when he had the good fortune to move to a property in Marin County, California that had a creek running through the back yard. There he conducted an informal and largely unconscious multiyear study of the life cycle of the frog, until high school interrupted his investigations with more worldly pursuits. Rich found his passion for laboratory science as an undergraduate at the University of California, Santa Cruz, studying the genetics of antibiotic resistance in bacteria in the laboratory of Cedric Davern and ribosome structure in the laboratory of Harry Noller. Rich began studying viruses as a graduate student at Yale University, where he conducted research on gene regulation during bacteriophage T7 infection in the laboratory of Joan Steitz, receiving a Ph.D. in 1975. As a postdoc at the Imperial Cancer Research Fund, in London, England from 1975-1977 under the mentorship of Robert Kamen, Rich studied transcriptional regulation of gene expression during infection by mouse polyoma virus, a DNA tumor virus. From 1977-1978 Rich undertook a second postdoctoral fellowship in the laboratories of Joseph Kates and William Bauer in the Microbiology Department at the State University of New York at Stony Brook, where he initiated his studies on the poxvirus vaccinia. Rich was an Assistant and Associate Professor of Biochemistry at the State University of New York at Buffalo from 1978 until 1990, when he moved to the University of Florida as a Professor in the Department of Molecular Genetics and Microbiology. Since 1977, Rich has used a genetic approach to study transcriptional regulation of viral gene expression and, more recently, virus assembly using vaccinia as a model system. Rich runs a relatively small research laboratory and still conducts his own experiments whenever possible. In both the laboratory and in the classroom, Rich teaches virology to graduate students, medical students and undergraduate students. Rich plans to remain at the University of Florida for the remainder of his formal career when he can once again turn his curiosity to less formal pursuits. There’s a creek in his back yard…
Rich first appeared on TWiV as a guest on episode #26, Poxviruses, in March of 2009 and after several return visits became a regular participant in February of 2010. Rich feels strongly that science is for everyone and that an understanding of the scientific basis of our existence and an appreciation for the methods used to gain that understanding is critically important for the future of the globe. Rich is grateful that TWiV provides an opportunity to communicate this passion to a broad audience of listeners.
Dickson D. Despommier, Ph.D.(TWiV, TWiP, Urban Agriculture) is Professor Emeritus of Public
Health in Environmental Health Sciences and Microbiology at Columbia University Medical Center. He is a microbiologist/ecologist by training, and for 27 years conducted laboratory-based research on molecular aspects of intracellular parasitism. Dick also teaches Parasitic Diseases, Medical Ecology, and Ecology 101. These courses deal with parasitism and its effects on large segments of the poor that live in the tropics. Controlling soil-based transmission cycles of helminthes that cause significant health problems throughout the world is of prime importance to Dick. Since it is generally agreed agriculture is solely responsible for so much environmental disturbance and serves as the interface for the transmission of geohelminths, one area of his focus has been on how to raise food without further encroachment into natural ecosystems. He established The Vertical Farm as a theoretical construct to look at the possibility of agricultural sustainability within cities. Sustainable urban life is now a major interest of Dick’s. Inventing new approaches to the raising of food within the confines of a large urban center is bound to be fraught with hidden pitfalls and caveats when starting out, particularly those of a technical and economic nature. However, he firmly believes that with enough input from multiple disciplines (e.g., industrial and soil microbiology, engineering, public health, policy making, urban planning, architecture, agronomy, plant genetics, economics), vertical farming could become a reality and thus replace most of what now passes for agriculture in many parts of the developed and under-developed world. If this were to come about, large tracts of land could then be returned to nature to do what it was supposed to do for us before we eliminated the hardwood forests of the eastern states. Restoring ecosystem services and functions is what Dick envisions as the charge to the next generation of public health professionals.
Alan Dove, Ph.D. (TWiV, @alandove) grew up near the small waterfront city of Annapolis, Maryland, and spent an inordinate amount of his childhood on and around boats. Fortunately, he also developed interests that offered genuine employment opportunities, including biology, chemistry, public policy, writing, computers, and electronics. After earning a bachelor’s degree in biology and chemistry from Towson State University in Baltimore County, he pursued – and with considerable effort, got – a Ph.D. in microbiology from Columbia University in New York City.
In 1997, Alan left laboratory research to become a science journalist, a job better suited to his short attention span and wide-ranging interests. His work appears in numerous publications, including the Webby-winning New York Academy of Sciences site, several of the Nature journals, and trade publications such as Drug Discovery and Development and Bioscience Technology. He blogs at Turbidplaque.
Nels Elde, Ph.D. (TWiEVO, @ElEarlyBird) is Assistant Professor of Human Genetics and Mario R. Capecchi Endowed Chair of Genetics at the University of Utah School of Medicine.

Nina Martin (Public Health United) aims to evaluate and improve public health communication and collaboration by uniting public health professionals from diverse backgrounds (each podcast will have guests from different fields). We will address common misperceptions and factors that contribute to the rift between public health professionals (especially between basic scientists and others) and the public. Lastly, we will directly connect to the public we are trying to help by interacting with people on the streets of Baltimore and by polling their public health knowledge and questions. These questions will be posed to the podcast guest-experts and we will spend time evaluating how well we communicate. By bringing together experts from different public health fields and directly connecting to the public, we hope to improve communication, collaboration, and confidence in our public health research.
In addition to pursuing her Immunology PhD at the Johns Hopkins School of Public Health, Nina actively engages the public in public health and science communication. She loves speaking to the public about science communication issues, especially topics that have taken on a political charge like vaccines and genetically modified organisms. She had a fantastic time speaking at TEDxMidAtlantic in DC last September on how forcing science into simple dichotomies, like true versus false or democrat versus republican, is really bad for our health. She has spoken at Ignite Baltimore about vaccine communication issues and how pro-vax’ers are just as bad as anti-vax’ers at communicating the facts.
Jesse Noar, Ph.D. (BacterioFiles) is a microbiology PhD from North Carolina State University who finds microbes continually fascinating.
In high school, an especially good biology teacher introduced Jesse to techniques of microbiological culture and assigned him to separate and identify the organisms in a mixed culture, which he found so enjoyable that he decided to make a career of studying bacteria.
In his undergraduate years at Cornell University, Jesse did well in his microbiology classes and also worked in several labs, gaining experience and research enough to complete an honors thesis. After graduating, he decided to remain in his current lab and gather enough data to publish his first scientific journal article.
With a few years’ worth of research experience, Jesse decided that it was time to aim for a PhD, and enrolled in the Microbiology graduate program at North Carolina State University, working in the lab of Dr. José Bruno-Bárcena. Funded by the College of Agriculture and Life Sciences at NCSU and by a NSF graduate research fellowship, he has researched a strain of nitrogen-fixing bacteria that produce hydrogen gas.
He’s always working on ways to see just how good for us bacteria can be, and in order to share his enthusiasm for discoveries made by others or himself, he created BacterioFiles.
Elio Schaechter, Ph.D. (TWIM) is an actively retired microbiologist, currently living in San Diego, California.

He has a deep love of teaching, and has been told that his natural habitat is the other side of the lectern. He has authored several textbooks and co-edited treatises. He continues to write. After retirement, he tried to satisfy his curiosity in broader microbiological phenomena, especially those related to ecology and symbiotic relationships. His hobby is wild mushrooms. For a short account of his activities, visit his home page.
Michael Schmidt, Ph.D. (TWiM) is Professor and Vice Chairman of Microbiology and Immunology, and Director, Office of Special Programs at the Medical College of South Carolina. Dr. Schmidt is leading
a team of infectious disease specialists, from three health sciences centers, and engineers, from industry, where they are assessing what role the microbes associated with objects that patients, health care workers and visitors encounter while in hospital play in the acquisition of a HAI. Through their first interventional study they established that the intrinsic microbial burden played a significant role in the acquisition of a HAI. Limited placement of cooper was found to reduce the burden by greater than 85% which resulted in a concomitant 58% reduction in HAI. These data served as the basis of his recent TEDx talk. Dr. Schmidt has been a member of the Communications Committee for the American Society for Microbiology, co-chaired the society’s career’s poster development, and helped revise the society’s public website, Microbeworld.org. He has led numerous, national workshops on the use of computers for instruction in medicine and microbiology and infectious diseases, has been a panelist on Science Friday broadcasted by National Public Radio and has been a content editor for Microbeworld radio, a daily radioshow/podcast produced by the society for the general public.
Kathy Spindler, Ph.D. (TWiV) is Professor of Microbiology and Immunology in the medical school at the University of Michigan. She came by her interest in science genetically: her parents were both chemists. Kathy had two inspiring science teachers in junior high school, and she always knew she wanted to major in biology, which she did at Purdue University. She moved to UC San Diego for her doctoral work, and she began working on viruses in her first rotation, with Dr. Masaki Hayashi. She joined that lab for the first part of her dissertation research, working on the single-stranded DNA bacteriophage FX174. Kathy completed her Ph.D. in the laboratory of Dr. John Holland, working on “Evolution of viral RNA genomes in acute and persistent infections,” using vesicular stomatitis virus. In 1981 she began her postdoc with Dr. Arnie Berk at UCLA, focused on the human adenovirus proteins encoded by E1A. Kathy moved to a faculty position at the University of Georgia (UGA) Department of Genetics in 1985, where she established studies of mouse adenovirus type 1 (MAV-1). This virus has molecular genetics with similarities to human adenoviruses, and yet it can be studied in its natural host, using the powerful genetic and immunological tools of the mouse model. At the end of 2001 Kathy moved to the University of Michigan, where her research into viral pathogenesis and host susceptibility to infection has expanded. She continues to teach undergraduates and graduate students, and she is currently the Chair of the Graduate Studies Committee in Microbiology and Immunology.
Kathy started her science outreach as a pen pal on science projects with elementary school children. She developed a summer genetics research program for visiting college students at UGA (SUNFIG). She currently is a member of the University of Michigan’s ADVANCE advisory board. ADVANCE began as an “NSF-funded project promoting institutional transformation with respect to women faculty in science and engineering fields,” and at Michigan it now has an expanded mission to promote diversity among faculty in all fields. Kathy served for five years on ADVANCE’s STRIDE committee, participating in workshops both at Michigan and around the country discussing practices to maximize the likelihood that diverse candidates will be identified, recruited, and promoted in the academy.
Kathy first appeared as a guest on TWiV on episode #158 in November 2011, “Wolverines go viral,” although earlier she had sent comments, suggestions of guests (especially women!), pick of the week suggestions to Rich, and even a photo that was used for an episode (#127, cold chain). After several return visits to TWiV, in August 2012 Kathy was invited to be a regular participant. She recommends TWiV to relatives, friends, and strangers as an easy way to hook them on virology; her modest (!) mission is to propagate knowledge of science to everyone. Kathy is happy to participate directly in spreading this knowledge virally through TWiV.
Michele Swanson, Ph.D. (TWiM) is a Professor in the Department of Microbiology & Immunology at the University of Michigan Medical School. Michele earned a B.S. in Biology from Yale, where she also
played collegiate field hockey and softball. She was introduced to the exciting world of experimental science as a research technician at the Rockefeller University in the lab of Samuel C. Silverstein, an expert in leukocyte cell biology who conducted seminal studies of Legionella pneumophila growth in macrophages. Michele developed her love of genetics as a graduate student, using Saccharomyces cerevisiae as a tool to study gene expression with Marian Carlson at Columbia and Fred Winston at Harvard. After a brief hiatus devoted to her two children, she began postdoctoral training with Ralph Isberg at Tufts and HHMI, where she developed cell biological methods to analyze the fate of L. pneumophila in macrophages. In addition to exploiting this pathogen as a genetic probe of macrophage function, her lab at Michigan investigates how metabolic cues govern L. pneumophila’s differentiation to specialized cell types equipped for intracellular replication, transmission between host cells, or persistence in the environment.
A source of pride to Dr. Swanson are the gifted PhD students, postdoctoral fellows and undergraduates she has had the privilege and pleasure of mentoring at the University of Michigan. There she is also Director of the Medical School’s Office of Postdoctoral Studies and a lecturer in the Infectious Disease Sequence. Michele is also honored to Chair the American Academy of Microbiology and co-author with TWiM host Elio Schachter and Drs. Fred Neidhardt and Gemma Reguera the ASM Press textbook Microbe.
Michele first appeared as a guest on TWiM in May 2013 on Episode #56: Live at ASM in Denver. She was delighted to have the opportunity to work with Vincent, who had taught her the wonders of virology during her graduate years at Columbia, and with Elio, the masterful Chair of the Department of Molecular Biology & Microbiology during her postdoctoral years at Tufts. Michele is committed to sharing the excitement and power of laboratory science not only with the taxpayers who fund our research and but also with the next generations of scientists.
