Stavroula Hatzios, PhD

Stavroula is an Assistant Professor of Molecular, Cellular and Developmental Biology and of Chemistry in the Microbial Sciences Institute at Yale University. A native of Blacksburg, Virginia, she received her B.S. in chemistry from MIT and conducted her graduate work with Carolyn Bertozzi at UC Berkeley. After earning her Ph.D., Stavroula completed a research fellowship in Uganda before pursuing postdoctoral work with Matt Waldor at Brigham and Women’s Hospital/Harvard Medical School. Outside of the lab, she has been a longtime volunteer with science outreach organizations and has performed widely as an oboist.

Postdoctoral Fellow 

  Alicia DeColli

Alicia DeColli, PhD

After obtaining her B.S. in Biochemistry from Stonehill College (Easton, MA) in 2013, Alicia joined the lab of Dr. Caren Freel Meyers at the Johns Hopkins University School of Medicine (Baltimore, MD) to pursue her PhD in Pharmacology and Molecular Sciences. In the Freel Meyers lab, Alicia uncovered the oxygenase activity of the attractive, yet under-exploited antibacterial target DXP synthase. This discovery enabled Alicia to further unravel the importance of conformational dynamics in catalysis which is facilitating the rational design of selective inhibitors of DXP synthase towards the development of novel antibiotics. In the Hatzios lab, Alicia is excited to begin investigating mechanisms of redox signaling at the host-microbe interface. Outside of lab Alicia enjoys dancing, volunteering, and exploring the outdoors.

Graduate Students 

  Maia Baskerville

Maia Baskerville

Maia is a third-year graduate student in the Department of Microbial Pathogenesis at Yale. She graduated summa cum laude from Wells College with a B.A. in biochemistry and molecular biology. As an undergraduate, Maia pursued viral genomics research with Dr. Keith Perry at Cornell University and studied viral regulation of immune cell differentiation with Dr. Gary Chan at SUNY Upstate Medical University. In the Hatzios lab, she is applying chemical probes to identify and characterize proteins selectively activated during Helicobacter pylori infection, as well as investigating the bacterium’s redox effects on host cells. Outside her scientific pursuits, she enjoys playing the piano, creating art, cooking, and maintaining her patterned sock collection.

  Danny Dumitrescu

Danny Dumitrescu

Danny was raised in Cary, North Carolina, and received his B.S. in chemistry from Duke University. During his undergraduate studies, Danny worked with Dr. Kenichi Yokoyama to elucidate the biosynthesis of nucleoside natural products produced by Streptomyces. As a third-year chemistry graduate student in the Hatzios group, Danny is now studying how pathogen-derived proteins and small molecules promote gastrointestinal disease.

   Elizabeth Gordon

Elizabeth Gordon

Elizabeth is a second-year graduate student in the Department of Molecular, Cellular and Developmental Biology. She was raised in Pensacola, Florida, and graduated with both a B.S. in Biology and M.S. in Medical Sciences from the University of Florida. There, she worked in the lab of Dr. Charles Wood investigating the presence and role of a fetal microbiome during late gestation. In the Hatzios lab, Elizabeth is studying redox signaling in gastric cells during H. pylori infection. Outside of lab, Elizabeth enjoys hiking, baking, and lounging in her hammock with a good book.

Katya Kovalyova

Katya (Yekaterina, Kat, Catherine, Katja, Katie, etc.) Kovalyova is a fourth-year graduate student in the Chemistry Department at Yale. She graduated from Columbia University with a B.A. in biochemistry and a minor in computer science. While at Columbia, she worked in the Sames lab on the development of fluorescent false neurotransmitters as tools for studying neuronal communication with synaptic resolution. Now in the Hatzios lab, Katya is applying chemical proteomic techniques to study redox signaling during H. pylori infection.

  Anna Seminara

Anna Seminara

Anna is a first-year graduate student in the Department of Microbial Pathogenesis. She graduated from the University of Maryland, College Park, with a B.S. in Biological Sciences with a concentration in Microbiology and high honors in Cell Biology and Molecular Genetics. While at UMD, Anna worked in the lab of Dr. Vincent Lee, studying how second messenger signaling nucleotides like cyclic-di-GMP interact with proteins. In the Hatzios lab, she will be investigating the biochemistry of redox-active small molecules in gastrointestinal bacteria. Outside of lab, Anna enjoys reading, embroidering, and going to the theater.
