Current Lab Members

Dr. Sarah Flowers - Assistant Professor and PI

Sarah did her Ph.D. at the University of Technology, Sydney, and The Rockefeller University in NY, where she gained strong mass spectrometry (MS) proteomics expertise in the Laboratory of Mass Spectrometry and Gaseous Ion Chemistry with Dr. Brian Chait. She then undertook a postdoc position at the Sahlgrenska Academy, University of Gothenburg, Sweden, with Dr. Niclas Karlsson which introduced her to glycobiology; the study of the identity and function of the glycans (sugars) attached to proteins. Sarah used her MS skills to successfully investigate the role of glycosylation in diseases of aging, particularly arthritis as well as autoimmune diseases including Sjogren’s syndrome, focusing on diagnosis. She developed the first selected reaction monitoring (SRM) (also called multiple reaction monitoring, MRM) method to characterize the entire range of O-glycans on a protein, applied to a protein critical in arthritis leading to a potential new diagnostic. She subsequently moved to Georgetown University and applied her skills towards understanding another critical disease of aging, Alzheimer’s disease, before starting her lab at the end of 2018. Sarah then accepted a tenure track position, moving the Flowers lab to the University of Virginia in June 2023.. Her work looks at the impact of glycosylation on the function of the APOE molecule, and how this might affect Alzheimer’s disease pathology and be important for very early AD diagnosis. The Flowers lab utilizes patient-derived iPSC disease models to understand carbohydrate modifications in human disease systems. Sarah is also interested in the impact of APOE isoforms on metabolism in different cell types involved in AD. Overall, her work is patient-focused, aiming to understand how changes in metabolism and carbohydrate post translational modifications impact pathogenesis and how these two critical factors interact, and translating this understanding into the early-stage diagnosis of diseases of aging like Alzheimer’s disease.

Sarah has an unabashed love for Lego and Funko Pop, and an impressive Grogu collection.

Dr. Harvey Fernandez - Assistant Professor

Harvey did his PhD at the University of New South Wales, Sydney, and then moved to the US and completed a postdoc in Missouri working on epigenetic mechanisms of gene regulation. He subsequently spent 4 years at the University of Gothenburg, Sweden, analyzing the impact of the glycoprotein, MUC1, on colorectal cancer. Moving back to the US, Harvey started his work at Georgetown University examining mitochondrial metabolism in cancer stem cells, and his extensive molecular biology, metabolism, stem cell and glycobiology expertise led to a collaboration with the Flowers Lab, which he joined in late 2018. His current work in the Flowers Lab involves utilizing patient-derived induced pluripotent stem cells to generate astrocytes, neurons, microglia and hepatocytes to analyze the influence of different APOE isoforms on the function of these cells, and how this affects Alzheimer’s disease pathogenesis. He is instrumental in a range of projects looking at how APOE genotype impacts cells as well as how its glycosylation affects its function. Harvey is both continually fascinated by science and hugely practical, which drives us to be inventive in a thoughtful way that makes the lab more productive and creative.

They have not discovered a sport that Harvey could not enjoy watching.

Dr. Dina Bai - Research Scientist

Dina is a research scientist in Bioinformatics.  She did her PhD in Developmental Psychology at UVA, studying the integration of visual and vestibular information to maintain posture.  After grad school, she moved into software engineering and scientific computing.  She re-joined UVA in 2000 as part of Donald Hunt’s biological mass spectrometry lab, where she used her scientific training and software/data analysis background to contribute to the study of the sequences of proteins and peptides, post-translational modifications and the development of new instrumentation. She joined the Flowers Lab in 2023,  and is applying her bioinformatics skills to research on Alzheimer’s Disease.

In her spare time, Dina hikes whenever she can, is addicted to jigsaw puzzles, and loves time with family.

She also is an expert on which bird feeders are squirrel proof (and also which ones are bear proof ie. none).

Ayushi Agarwal - Research Assistant

Ayushi is a research assistant, who just finished a year as an undergrad in the lab and we obviously didn’t scare her enough, so she decided to stay, which we are very happy about! She graduated from the University of Virginia in the Spring of 2024. During her time at UVA, she majored in Cognitive Science and Neuroscience. So far, Ayushi has spent most of her time in the lab learning more about astrocytes and IPSCs, but has very proficiently moved onto her own project that is moving along very well. Her future career goal is to become a neurologist, which we think she will excel at because she is very smart and has the best enunciation as well as very neat writing.

She loves baking, plants, and Taco Bell's fire sauce, as well as making super creative halloween costumes.

Xiaoyu (Amy) Wang - Research Assistant

Amy started as a Research Assistant in the Flowers lab in August ‘24. She received her Bachelor’s degree in physiology and pharmacology from the University of Saskatchewan, Canada. After graduation, she worked for the Institute of Clinical Pharmacodynamics in Schenectady, NY as a lab technician for 2 years. She was working on antimicrobial susceptibility carrying out PK, PK-PD in vitro and in vivo testing, and while she enjoyed it she wanted further challenges so decided to join an academic research lab, which is how we were lucky enough to hire her. Alzheimer’s disease and genes are totally new topics for her, and she is very excited to learn and work with cells (especially as they smell better than bacteria). She deeply hopes she can learn more new techniques without destroying the lab.

She is a huge cat lover and has 4 cats at home that she is smitten with (the white one is a bit naughty though). She loves working out (weight training only, no cardio please), and snowboarding. Let’s hope she doesn’t break anything this snow season.

Amisha Sahni - Undergraduate student

Amisha is a rising 4th year student who joined the lab at the start of her third year. She is a Neuroscience major at University of Virginia. She grew up in Roanoke, VA, and spends her time in the summer volunteering as an EMT for her local rescue squad, where she got first hand experience working with patients with different neurological diseases. Amisha was first introduced to iPSCs from learning about it in her Introduction to Cell Biology course, and was excited to work with them further in the Flowers Lab. She is currently optimizing the generation of iPSC derived cardiomyocytes, and having a great time watching them beating. She is excited to do more extensive analyses of them in the coming semester.

Amisha loves to dance salsa, bachata and cha-cha, and hasn’t injured any dance partners in months!

Anjali Desai - Undergraduate student

Anjali is a 4th year undergraduate student majoring in Biology and minoring in Bioethics. She is from Ashburn, VA and her family recently got a mini husky puppy named Selah! Outside of the lab, Anjali is a member of Remote Area Medical @UVA which is an organization that volunteers at and hosts free healthcare clinics. Anjali also plays tuba in the Cavalier Marching Band! This is her 11th year playing the tuba and hopefully her last year  because she can’t handle the back pain anymore. This is Anjali’s first time in a research lab at UVA and she has enjoyed every aspect of it. She has learned so much in just a few months all thanks to the help of all the amazing and kind people in the lab! She is now working with iPSCs and can’t wait to see what else she’ll learn. 

Anjali loves watching movies with her roommates, hanging out with her puppy, making sweet treats, and wants to learn how to cook more because right now she only knows how to make pasta!

Khalilah Ellison - Undergraduate student

Khalilah is a third-year majoring in Neuroscience at the University of Virginia. She recently joined the lab this semester and is loving it so far! Khalilah is from the Eastern Shore of Virginia, a small peninsula on the East coast of Virginia. The Shore is a very small area, so coming to UVA has introduced her to many concepts and broadened her knowledge and experience widely. The Flowers lab became one of those new experiences that she was very eager to get started in. Khalilah’s mother is a home health aide, and she often grow close to many of her patients, many of which suffer from neurological diseases such as Alzheimer’s, so she has seen the effects of such diseases firsthand for the majority of her life. Her observations motivated her to pursue a career in the health field and learn the why and how behind neurological disorders.

Outside of what drives Khalilah academically, she loves spending her free time engaging in all things arts and crafts, bullet journaling, and as of recently cooking as she tries out new vegan meals. Khalilah likes the title of “self-proclaimed hobby hopper” to be very fitting since she can never stick to one thing consistently for more than a month.

Deeya Patel - Undergraduate student

Deeya is a second-year majoring in Neuroscience and minoring in Data Analytics. She is from Harrisonburg, VA, and is one of multiple undergrads who have joined the lab this year. She is enjoying learning more about scientific research and the different lab techniques involved.

Claire is currently working on a project studying the APOE isoform differences in cardiomyocyte mitochondrial function.

Outside of the lab, Claire loves to run, go on hikes, and paint with watercolors. She just returned from a semester abroad studying at the University of New South Wales in Sydney, Australia (Editors note: Harvey was impressed with this because he thinks it is the best university in Australia. [Superseding Editor’s note - Sarah does not agree]). While abroad, Claire went scuba diving in the Great Barrier Reef and road-tripped through New Zealand.  

Catherine Goldstein - Undergraduate student

Catherine is a 2nd year undergraduate student from Alexandria, VA, majoring in Neuroscience with a minor in Psychology. She is currently studying on the pre-med track and hopes to pursue psychiatry. Catherine recently joined the Flowers Lab and is very excited about this opportunity to learn more about the APOE4 genotype and its role in Alzheimer's Disease pathology, diagnosis and potential therapies. Prior to joining the lab, Catherine worked as a research intern at Marymount University's Center for Optimal Aging, where she learned from researchers, practitioners and educators about improving the science of human aging. Outside of the Lab, Catherine volunteers with Madison House’s Adopt a Grandparent program, which involves weekly visits to memory care centers in Charlottesville and developing relationships with the residents. Catherine enjoys spending time with her friends and family (including her 8-year-old yellow lab, Olive), completing the daily New York Times "Connections" and "Wordle" puzzles, reading a good psychological thriller or mystery, and going on long runs. 

If you are looking for Catherine on a Sunday afternoon, she's probably at Trader Joe's, stocking up on dark chocolate peanut butter cups, butternut squash mac and cheese (a new favorite!), and "everything but the bagel" seasoning for the upcoming week.

Mi’Amor Stewart - Undergraduate student

Mi’Amor Stewart is from Phoenix, Arizona, and is looking to major in neuroscience with a possible minor in finance on a pre-med track, with hopes of pursuing neurosurgery. Coming to UVA, Mi’Amor knew prior she wanted to get involved with research. The study of Alzheimer's and how the genes affect this quickly caught her attention and intrigued her, and so she wanted to pursue this. She is currently working with the Dana in the lab and is and learning about the association between APOE and the ABCA7. Since coming to UVA, she has joined an orchestra, become part of a volunteering community, and started a new job. Outside of her extracurriculars, Mi’Amor enjoys playing the violin, karaoke, long drives, traveling, making lists, and shopping. Fun Fact: Coming to Charlottesville, she was so sure it was going to snow every winter until she got the upsetting news it barely snows; she was so excited for the snow. (The rest of the lab have assured her she will definitely see plenty of snow before her degree is over - or at the very least more than she saw in Arizona).

Irene Wang - Undergraduate student

Irene is a second year student from Auckland New Zealand, double majoring in Neuroscience and English literature. She is studying on the premed track with the hopes to study surgery - (MD Phd???). Irene is especially interested in studying drugs to slow the onset of Alzheimer diseases and other effects APOE4 has on the body. Outside of the lab Irene is passionate about accessibility and inclusion and involved with Recreational therapy, international students programs,  the Jefferson Literary and Debating Society, American Medical Students Association, and her residential college. 

Irene hates running on its own but enjoys playing tennis and football (Soccer!). Irene also enjoys overnight backpacking and sea kayaking! Irene likes writing poetry, watching American history cartoon videos,  stand-up comedy, and Trader Joes mac and cheese. Along with her other pursuits, Irene is on a constant journey to find the perfect mac and cheese recipe but is unfortunately limited by the amount of mac and cheese she can eat in a day.
