Andrew Flyak, PhD - Principal Investigator

Andrew Flyak, an assistant professor in the Department of Microbiology and Immunology, began his research career in Ukraine. He earned a BS degree from the Taras Shevchenko University of Kyiv. He then moved to Nashville, Tennessee, and joined the PhD program in Microbiology and Immunology at Vanderbilt University. While at Vanderbilt, he determined how Marburg and Ebola viruses are neutralized by antibodies isolated from survivors of these deadly infections. During his postdoctoral studies at the California Institute of Technology, he used human antibodies to overcome a long-standing hurdle in Hepatitis C virus vaccine design – the crystallization of an intact form of the Hepatitis C virus envelope glycoprotein.

Andrew loves spending time with his family and running Ithaca trails.

  • Postdoctoral Fellow

    Xander was born and raised in the Ithaca, NY area and completed his bachelors at Hobart and William Smith Colleges. He went on to earn his PhD in chemistry and chemical biology in the labs of Dr. Andrew Fisher and Dr. Peter Beal at the

    University of California, Davis where he used structural biology to develop site-directed RNA editing therapeutics. In the Flyak lab, he is interested in structurally characterizing broadly neutralizing antibodies to aid in the development of a vaccine for Hepatitis C.

    Outside of the lab, Xander enjoys traveling to National Parks, hiking, weightlifting, gardening, and homebrewing craft beer.

  • Postdoctoral Fellow

    Rajat is from India and completed his PhD in computational biology at the Indian Institute of Technology, Delhi. He holds a B.Tech. in Chemical Engineering from the same institute. Rajat has extensive experience in computational drug discovery and characterizing the function of biomolecules, such as proteins and lipid membranes, using molecular simulations. At Flyak Lab, he aims to advance vaccine design for the hepatitis C virus through a multidisciplinary approach combining computational and experimental methodologies.

  • BMCB Graduate Student

    Sekyere Boateng is from Ghana, West Africa, and graduated from the Kwame Nkrumah University of Science and Technology (KNUST) in Kumasi with a Bachelor of Science degree in biochemistry and biotechnology. He earned a master's degree in chemistry from Tennessee Technological University, where he worked in Dr. Zhan's lab, identifying novel protein-protein interactions in the Mitogen-Activated Protein Kinase (MAPK) pathways. He is thrilled to be a part of the Flyak Lab and is looking forward to furthering his interests in structural biology and immunology.

  • BBS Graduate Student

    Anastasia (Stasha) Rup was born and raised in Vermont. She then completed her bachelor's at Rochester Institute of Technology. After graduation, she worked as a lab technician for two years at Cornell before joining the BBS PhD program. In the Flyak lab, she is interested in further characterizing B cells that generate broadly neutralizing antibodies in response to vaccines. 

  • BBS Graduate Student

    Katelyn was born and raised in Camarillo, CA. She completed her undergraduate in Microbiology at the University of California, San Diego in 2023. While an undergraduate, she studied in a molecular biology lab and focused on elucidating mutant peroxisome production pathways in Saccharomyces cerevisiae. In the Flyak lab, she hopes to understand the underlying relationship of chronic hepatitis C virus infection and the later development of B cell lymphoma, furthering her interests at the intersection of virology and immunology. In her free time, Katelyn enjoys yoga, rock climbing, reading, and tending her garden.

  • BMCB Graduate Student

    Rahul Ribeiro is from Rochester, NY, and he graduated from the University of Michigan in Ann Arbor with Bachelor of Science degrees in Biochemistry and Economics. At Michigan, he did his undergraduate thesis in the lab of Dr. Kristen Verhey in the department of Cell and Developmental Biology, where he studied how siRNA knock-downs of microtubule associated proteins influence microtubule damage. He also worked in Dr. Dipankar Ray’s lab in the department of Cancer Biology, where he identified a novel interaction between the GRAIL and calcineurin proteins and how it might be related to EAC. He is excited to join the Flyak Lab and is interested in pursuing knowledge in immunology and structural biology of antibodies.

    In his free time, Rahul enjoys being with friends, nature, running, cooking, sweets, Pokémon Go, and Fortnite.

  • Research Technician

    SarahBeth was raised in Deerfield, NY and graduated from Russell Sage College for Women in Troy, NY with a double degree in biology and theatre, earning program and project honors.  She comes to Cornell from Upstate Medical University where she had been a technician for many years.  Her passion is microscopy and the translation of molecular biology into treatments to benefit humanity. She was most recently working with extracellular matrix degradation in metastasis of kidney cancer and is excited to translate her work into liver research.  She loves being a technician and lab manager, which allows her to work at the bench, making beautiful science, and to have the opportunity to train students from whom she learns as much as she teaches.

    In her free time, SarahBeth loves to design and make costumes for local theatre, and clothes for herself and her children.  She also does far too many other crafts but believes it’s not hoarding if it’s craft supplies. She also is a passionate cheerleader for her children and their activities.

  • Undergraduate Student

    David is a freshman majoring in Global and Public Health Sciences. Aspiring to attend medical school, he has experience in Emergency Medical Services, as an Ophthalmology Technician, and in clinical/wet-lab research. Prior to joining the Flyak Lab, David conducted two independent glaucoma research projects: one focused on mRNA expression of gene therapy treatments, and the other on the effectiveness of antisense oligonucleotides within cultured human scleral fibroblasts. He has further interest towards global health and the implementation of more equitable healthcare research.

  • Undergraduate Student

    Anousha is a sophomore majoring in Biomedical Engineering and minoring in Business. After undergrad, she plans to enroll in a PhD program and later work in the biotech industry. Her experience includes an internship at Evolve Immune Therapeutics focused on assisting her mentor in developing a T-cell engager. She is also a wet-lab member of Cornell iGEM, a synthetic biology project team that works on a different project every year, focusing on genetically engineering bacteria. In the Flyak lab, she works with Rahul Ribeiro and is excited to learn more about immunology. 

  • Undergraduate Student

    Andrea is a sophomore from Mexico majoring in Biological Sciences, and minoring in Infectious Disease Biology and History of Art. Prior to joining the Flyak Lab, she participated in research on the pathology of tuberculosis, which further deepened her interest in immunology, microbiology, and infectious diseases. Andrea plans to pursue a PhD and hopes to work in the pharmaceutical industry on vaccine and therapeutic development. She is enthusiastic about expanding her training and contributing to the lab’s research environment.
