MicrobeTV was founded in 2015 by Vincent Racaniello, a professor of Microbiology and Immunology at Columbia University. Vincent began his first podcast, This Week in Virology (TWiV), in September 2008 with Dickson Despommier, father of the Vertical Farm. Although Vincent viewed the creation of a science podcast as an experiment, he was surprised when people began to listen. Since then, MicrobeTV has become a 501c3 nonprofit organization and has continued to create accessible life science-based podcasts in line with our mission of providing free science education to everyone. Now more than ever, people in our world need access to accurate science so they’re able to identify disinformation. If you have the means and would like to help keep MicrobeTV free for all, please donate today,

Vincent (@profvrr) is a Professor of Microbiology at Columbia University Medical Center. He has been studying viruses for over 30 years, starting in 1975, when he entered the Ph.D. program in Biomedical Sciences at Mt. Sinai School of Medicine of the City University of New York with a focus on influenza viruses. In 1979, he joined the laboratory of Dr. David Baltimore at Massachusetts Institute of Technology, for postdoctoral work on poliovirus. In 1982 Vincent joined the faculty in the Department of Microbiology at Columbia University College of Physicians & Surgeons in New York City. There he established a laboratory to study viruses, and to train other scientists to become virologists. Over the years his laboratory has studied a variety of viruses including poliovirus, echovirus, enterovirus 70, rhinovirus, and hepatitis C virus. As principal investigator of his laboratory, he oversees the research carried out by Ph.D. students and postdoctoral fellows. He teaches virology to graduate, medical, dental, and nursing students. His virology lectures are available online at iTunes UniversityYouTube, and Coursera.

Vincent entered the world of social media in 2004 with virology blog, followed by This Week in Virology. Videocasts of lectures from his undergraduate virology course are on iTunes University and virology blog. You can find him on WikipediaTwitterGoogle Plus, and Facebook. 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. His Wildy Lecture provides an overview of how he uses social media for science communication.

Nels Elde, Ph.D.

Nels is Associate Professor of Human Genetics and Mario R. Capecchi Endowed Chair of Genetics at the University of Utah School of Medicine. Nels grew up in Minneapolis, the City of Lakes, along with a sister, brother, and a multitude of pets. After graduating from Carleton College with a major in Biology, he continued as a technician in the lab of Stephan Zweifel, pursuing genetic studies in yeast and the fungus of leaf-cutting ants.

As a Ph.D. student in the lab of Aaron Turkewitz at the University of Chicago, his thesis research focused on molecular genetic and evolutionary studies of membrane traffic in the model ciliate Tetrahymena thermophila.

As a post-doc in the lab of Harmit Malik at the Fred Hutchinson Center, Nels developed a research program studying pathogen-driven evolution as an Ellison Medical Foundation Fellow of the Life Sciences Research Foundation and with an NIH Pathway to Independence Award investigating the evolutionary potential of the model poxvirus vaccinia.

After opening the lab in 2011, Nels was named a Pew Scholar in the Biomedical Sciences, a Kavli Foundation Fellow, and an Associate Editor for PLOS Pathogens. Nels received the 2015 Ann Palmenberg Junior Investigator Award from the American Society for Virology. The Elde lab uses host-pathogen interactions to study the evolutionary process and evolutionary approaches to understand the selective forces shaping cellular pathways.

Nels’ research has been featured on TWIV and TWIM, including an appearance on TWIV #234, “Live in Denver” at the annual American Society for Microbiology meeting in 2013. As co-host of TWiEVO Nels has achieved the coveted “TWifecta”, where he now strives to highlight exciting research emerging at the interface of evolutionary and experimental biology.

An active clinician and internationally invited speaker lecturing for multiple organizations, including the University of Glasgow, the Peace Corp, University of Minnesota, Foundation for International Medical Relief of Children (FIMRC), Floating Doctors, and Remote Care Education, as well as for other groups in Asia, the Caribbean, Central America, Africa, and India. One of the hosts of the popular podcasts This Week in ParasitismThis Week in Virology, and The IDPuscast. One of the authors of Parasitic Diseases, now in its 7th Edition with thousands of copies distributed to over 100 countries worldwide. His non-profit organization Parasites Without Borders shares office space with MicrobeTV.

Amy Rosenfeld

Amy Rosenfeld, Ph.D. (Q&A) is Principal Investigator at the Center for Biologics Evaluation and Research of the U.S. Food and Drug Administration. She completed her Ph.D. in 2005 with Vincent Racaniello and returned to Columbia University 10 years later to continue her work on enteroviruses as the Associate Professor of Microbiology and Immunology.

Her recent work has demonstrated that neurovirulence of EV-D68 is not a recently acquired phenotype, and that antibody responses to enteroviruses are cross-reactive, a property not previously appreciated. She has appeared numerous times on TWiV and is also host of Q&A with A&V, a live stream program on the MicrobeTV network.

Elio Schaechter

Elio Schaechter

Elio Schaechter, Ph.D. (TWIM) is an actively retired microbiologist, currently living in San Diego, California.

Michael Schmidt

Michael Schmidt

Michael Schmidt, Ph.D. (TWiM) is the Professor and Vice Chairman of Microbiology and Immunology and Director of the 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. This team assesses what role the microbes associated with objects that patients, health care workers, and visitors encounter while in hospital play in the acquisition of an HAI.

Through their first interventional study, they established that the intrinsic microbial burden played a significant role in the acquisition of an HAI. Limited placement of cooper was found to reduce the burden by greater than 85%, resulting 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 careers poster development, and helped revise the society’s public website, He has led numerous, national workshops on the use of computers for instruction in medicine, 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 radio show/podcast produced by the society for the general public.

Michele Swanson

Michele Swanson

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 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.

The gifted Ph.D. students, postdoctoral fellows, and undergraduates Dr. Swanson has had the privilege and pleasure of mentoring at the University of Michigan are source of pride to her.  She is also the 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 but with future generations of scientists.
