Noor Bala
Ph.D. Student, Mentor - Dr. Deborah Fowell 
Hi! I am a second year Immunology and Infectious Disease PhD student in Dr. Deborah Fowell's lab. I study the spatial restriction of T-cell activation in inflamed/infected tissues and how that leads to pathogen control. I use multiphoton microscopy to look deep into the inflamed tissue of live mice and characterize the events that make T-cells tick as they clear pathogens. Before my PhD, I was a research scientist at Amgen San Francisco where I worked on the pharmacokinetics and drug metabolism of immunotherapy drugs. I am originally from California where I received my M.S. from CSULB and B.S. from UCLA. When I am not in the lab, I like to bake challenging pastries, work on some DIY projects, and hang out with my husband and two cats.

Eric Gelsleichter
Ph.D. Student, Mentor - Dr. Hening Lin 
Hello, everyone! I am a soon-to-be-second-year PhD student in the BBS program. I recently joined the lab of Hening Lin in the Department of Chemistry and Chemical Biology, where I will study how certain post-translational protein modifications contribute to the pathogenesis of autoimmune and chronic inflammatory diseases. I was a first-generation college student, and I grew up in a small rural community just outside Scranton, PA. I have a BS in chemistry from King’s College (Wilkes-Barre, PA), and I have a DVM from Virginia Tech (Blacksburg, VA). Throughout my undergraduate and veterinary school years (and throughout the time between), I participated in research spanning the chemical and biological sciences. After veterinary school, my wife, two daughters, and I lived just outside Syracuse, NY for 6 years, where I worked as a small-animal veterinarian prior to starting grad school at Cornell. Beyond my professional life, I love spending time with my wife and daughters, especially doing anything outdoors or exploring our surroundings. Once upon a time (i.e., prior to being a father of young children), I had many other interests that I someday hope to recapture (hiking/backpacking; camping; canoeing/kayaking; fly fishing; nature photography; fossil and rock collecting; learning to play guitar; learning music theory; history of science; history of medicine; traveling).
Megan Keller
Ph.D. Student, Mentor - Dr. Tobias Doerr
Hello, I am a second-year Ph.D. student in the Biomedical and Biological studies program! I recently joined the Doerr lab, working on bacterial cell wall physiology and how these contribute to antibiotic resistance. I grew up in Wichita, Kansas, but attended Florida Gulf Coast University to get my degree in Biology. There, I had the privilege to conduct research on the use of stilbenes to inhibit the migration of breast cancer cells. Coming to Cornell, I became interested in other antibiotics and their effects on Gram-negative bacteria. The Doerr lab was perfect for me, utilizing a combination of genetics, microscopy, and microbial techniques to answer these big questions. I also have a passion for science communication and outreach, and love to volunteer. Outside of lab, I enjoy exploring all the gorgeous trails that Ithaca has to offer, getting coffee with friends, and cuddling my cat, Luna, while watching movies.
Sebastian Gonzalo Llanos Soto
Ph.D. Student, Mentor - Dr. Renata Ivanek
Ph.D. Student, Mentor - Dr. Renata Ivanek
I come from Chile, a long and thin country located in South America, a land of volcanoes, penguins, and the finest wines. Most of my experience prior to joining the BBS program has been with parasites and infectious diseases of Chilean wildlife. I came to Ithaca with my dearest wife and two cats and we are enjoying our time here so far. Recently, I joined the Epidemiology and Food Systems Laboratory supervised by Dr. Renata Ivanek. There, I plan to learn epidemiological and mathematical modeling tools to study zoonotic disease transmission in agricultural settings. Learning German (and hopefully other languages), understand how the US history influenced society and politics in my country, and improve my communication skills are among my personal interests for the upcoming years. My hobbies include photography, ice cream, pet my cats and I have a deep interest in traveling (although not something that I could do right now).
Hector Loyola Irizarry
Ph.D. Candidate, Mentor - Dr. Ilana Brito 
Hi! I am a second-year student in Molecular and Cellular Medicine in the Brito Lab, where I study how the gut microbiome can cause disease and possible ways to engineer it to improve host health. I'm from the beautiful island of Puerto Rico, where I grew up and did my undergraduate studies. During my free time, I like to play video games and watch movies. If it's a nice day outside, you might catch me playing soccer or hiking!
Alexandra Molina
Ph.D. Student, Mentor - Dr. Alexander Travis 
Alexandra is a third year PhD student from the College of Veterinary Medicine Biomedical and Biological Sciences with a concentration in Zoology and Wildlife Conservation. She is also a joint graduate trainee with the Smithsonian National Zoo and Conservation Biology Institute. She graduated in 2019 from UCLA with a B.S. in Ecology, Behavior, and Evolution and has a research history in studying urban mammalian epidemiology and chimpanzee behavior. Now, her research is primarily composed of voltage-gated calcium channel Cav2.3 and its protein subunits’ contributions to the dynamics of murine sperm capacitation. In the future, she hopes to improve cryopreservation techniques to increase sperm longevity, better sperm quality, and prevent cryocapacitation from inhibiting conservation breeding goals.
