Alison Criss, PhD Associate Professor

Alison Criss, PhD

Alison Criss, PhD — Associate Professor

Alison received her PhD from Harvard Medical School on Salmonella infection of polarized epithelial cells. As a postdoctoral fellow at Northwestern University, she investigated the process of gonococcal pilin antigenic variation and developed new approaches for studying gonococcal interactions with human neutrophils. Her lab investigates the mechanisms underlying survival of gonococci to neutrophils, which allow the bacteria to evade innate immune-mediated clearance.

Asya Smirnov, PhD Research Scientist

Asya Smirnov, PhD

Asya Smirnov, PhD — Research Scientist

Asya received her PhD in Animal Sciences from the Hebrew University in Jerusalem in Israel. As a postdoctoral fellow at Cornell University, she studied the mechanisms of C. trachomatis interaction with host cells. In the Criss lab, Asya has examined how N. gonorrhoeae suppresses neutrophil ROS production. She developed an imaging flow cytometry protocol for measuring bacterial phagocytosis and is using it to discover how N. gonorrhoeae is engulfed by neutrophils.

Stephanie Ragland Graduate Student

Stephanie Ragland

Stephanie Ragland — Graduate Student

Stephanie received her bachelor’s degree in Biology from Virginia Commonwealth University in 2009. She worked as a research specialist with Dr. Jason Carlyon at VCU investigating Anaplasma phagocytophilum infection of granulocytes. Stephanie entered the BIMS graduate program at UVA in Fall 2012 and joined the Criss lab in Spring 2013. Her research explores how modifications to peptidoglycan affect Neisseria gonorrhoeae interactions with neutrophils.

Jacqueline Stevens MSTP Student

Jacqueline Stevens

Jacqueline Stevens — MSTP Student

Jacqueline received her degrees in Biochemistry and French from the University of Virginia in 2012. She entered the MSTP program in Fall 2012 and joined the Criss lab in Spring 2014. Her studies are examining neutrophilic inflammation initiated by Neisseria gonorrhoeae infection.

Allie Palmer

Allie Palmer — Graduate Student

Allie received her BS in Biology from Allegheny College in 2014 and her MSc in Microbiology from Clemson University in 2016. She joined the Criss Lab in 2017. Allie’s research explores how opacity protein expression by Neisseria gonorrhoeae affects bacterial interactions with primary human neutrophils.

Jocelyn Ray

Jocelyn Ray — MSTP Student

Jocelyn received her undergraduate degree from William and Mary in 2014 and performed postbaccalaureate research at the National Institutes of Health before matriculating into the UVA MSTP in 2015. Jocelyn joined the Criss Lab in 2017. Her research investigates how Neisseria gonorrhoeae acquires essential metals from human metal-sequestering proteins to overcome nutritional immunity.

Mary Gray, Lab Manager

Mary Gray – Lab Manager

Prior to joining the Criss Lab, Mary managed and performed research in the lab of Dr. Erik Hewlett in the Division of Infectious Diseases and International Health in the UVA Department of Medicine. In the Criss Lab, Mary is investigating the factors that mediate neutrophilic inflammation and bacterial survival after Neisseria gonorrhoeae encounters neutrophils.

Urmila Barathan

Urmila Barathan

Urmila Bharathan — Undergraduate Fellow

Urmila is a Biology major at the University of Virginia. Her research project examines how N. gonorrhoeae proteins that help confer antibiotic resistance can enhance bacterial survival from neutrophils.

Katie Hill

Katie Hill — Undergraduate Fellow

Katie is a Biology and Bioethics major at the University of Virginia. Her research investigates how genes contributing to “superbug” N. gonorrhoeae affect bacterial resistance to killing by neutrophils. Her thesis research investigates the bioethical implications of the stigma associated with sexually transmitted infections as it affects healthcare in vulnerable populations.

Rhea Kapania

Rhea Kapania  — Undergraduate Fellow

Rhea is a Nanomedicine major at the University of Virginia. Rhea is working with the Criss and Columbus labs to functionalize liposomes with opacity proteins from N. gonorrhoeae and investigate their interactions with human cells.

Former Lab Members

Sam Clark

Sam Clark — Laboratory Specialist

Sam graduated from the University of Mary Washington in May 2016. His research will explore mechanisms of N. gonorrhoeae resistance to killing by neutrophils.
