Houston, we definitely do NOT have a problem…with interviewing Dr. Kate Rubins, NASA astronaut.  Dr. Rubins is a virologist who has spent over 300 days in space, performing experiments aboard the International Space Station, where she was the first person to sequence DNA in space.

We caught up with Dr. Rubins at the Neutral Buoyancy Lab in Houston, where she discusses what it felt like the first time she saw the earth from space, some of the difficulties in performing research without gravity, how to study the microbiome of the ISS, how the international inhabitants of the ISS communicate with each other, and the spur-of-the-moment event that led to her becoming an astronaut.

Dr. Hyun Jung Kim, an Assistant Professor at Cleveland Clinic specializes in coaxing human cultured cells to differentiate and form tissues resembling the gastrointestinal tract, in order to study microbe-GI interactions. 

Dr. Kim discusses his surprising discovery of how common immortalized cultured cells can differentiate and form something that resembles a gut-on-a-chip, how these guts-on-a-chip can be used to study diseases like inflammatory bowel disease and colorectal cancer, how the addition of a microbiome to the gut-on-a-chip allows the bacteria to retain diversity unlike in a test tube, how the gut-on-a-chip could be valuable for personalized medicine, and the things he misses about Texas since moving from there.

Plague and anthrax are feared diseases due to high mortality rates following pulmonary exposure, and both are considered potential bioweapons. 

Dr. Virginia Miller, professor at the University of North Carolina at Chapel Hill and ASM President, studies plague, as well as other Gram negative bacteria. Dr. Theresa Koehler, emeritus professor at UTHealth Houston and ASM president-elect, is an expert in anthrax. 

microTalk caught up with Dr. Miller and Dr. Koehler at ASM Microbe 2023 in Houston to discuss these biothreat agents.

Dr. Miller discusses why she studies plague, the differences between bubonic and pneumonic plague, why Klebsiella pneumoniae poses a growing health threat, and what it was like being John Mekalanos’ first Ph.D. student.

Dr. Koehler discusses why anthrax is considered a potential bioweapon, why significant scientific progress was made following the anthrax attacks of 2001, why gardeners shouldn’t worry about catching anthrax, and her first failed experiment.  Both discuss their vision for ASM and the role it plays in microbiological research and society.

Dr. John Coates, a professor at the University of California Berkeley specializes in environmental microbiology and how microbes can be utilized to resolve problems in industry. 

microTalk caught up with Dr. Coates at the ASMicrobe conference in Houston and discussed his research in applied and environmental microbiology. 

Dr. Coates discusses an unexpected discovery of how microbes drive the iodine cycle on earth, how sequencing microbes in the oceans has been beneficial for identifying novel biochemical activities, how climate change has stimulated his research into the “bioeconomy”, why he’s optimistic that science can mitigate the effects of climate change, and how Berkeley is a remarkable place to do science.

The study of evolution has experienced a tremendous revolution with the advances in current sequencing technologies enabling e.g. rapid whole genome sequencing. 

Dr. Vaughn Cooper, a professor at the University of Pittsburgh who studies evolution in microbes, has taken advantage of these technologies to delve into how microorganisms adapt and evolve in different environments. microTalk caught up with Dr. Cooper at the ASM Microbe conference in Houston and discussed microbial evolution with him. 

Dr. Cooper discusses the power of next generation sequencing for the study of evolution, how mutation rates affect evolution, how providing hands-on evolution experiments to high school students can stimulate the next generation of scientists, how scientists need to work to combat public distrust of science, how antibiotic resistance evolves in the presence of immunodeficiency, and how his initial experience with baculoviruses hooked him into a lifelong study of evolution.

Malaria continues to have a significant impact on humans. The Plasmodium parasites are transmitted through mosquito bites, and the disease has a tremendous impact on global health.

Dr. Debopam Chakrabarti, a professor at the University of Central Florida who specializes in malaria. Dr. Chakrabarti discusses the history of the search for antimalarials, the problem of parasite drug resistance, how undergraduates can help to discover the next antimalarials, whether eradication of mosquitoes will eliminate malaria, and his challenging passion in growing roses in Florida.
