Principal Investigator

Jacqueline Kimmey

Jacqueline Kimmey, PhD 

Assistant Professor, METX (2019 - present)


Fun fact: if all the cars break down, you'll find her commuting on horseback. 

Area of focus: all the areas!

Jacqueline began her career at UCLA where she studied heme acquisition in Mycobacterium tuberculosis in the lab of Marcus Horwitz, MD. She did her graduate studies at Washington University in St. Louis with Christina Stallings, PhD studying autophagy-independent functions of ATG5 in controlling neutrophil mediated susceptibility to M. tuberculosis. As a postdoc she worked with Victor Nizet, MD at UCSD exploring how host responses dictate outcome of acute bacterial infections such as those caused by Streptococcus pneumoniae, Group A Streptococcus (GAS), Group B Streptococcus (GBS), and Staphylococcus aureus. Jacqueline's training has been generously supported by various training and mentorship programs including UC LEADS, MARC, NSF GFRP, and UC PPFP. In 2019, she was honored on the Forbes' 30 under 30 list (Science).

Graduate Students

Raina Sacksteder.png

rsackste <at> ucsc.edu

Raina graduated from Reed College in 2020 with a B.A. in Biology. She completed her undergraduate thesis in the Cerveny Lab, where she studied the gene targets of retinoic acid during retinal neurogenesis in the developing zebrafish eye. A summer position in the Ott Lab at UCSF sparked her passion for host-microbe interactions, which lead her to pursue a PhD in Microbial Biology and Pathogenesis at UCSC and join the Kimmey Lab in 2021. Her research uses zebrafish to understand how infection alters the circadian clock.

MS Student, METX (Joined lab 03/2021)

Fun Fact: She runs the Etsy shop FrogsOnSwings!

Area of focus: mechanism of circadian clocks in zebrafish, impact of Spn exposure 

Ask me to help with: zebrafish, Tol2 transgenesis, circadian clock

Catherine graduated from New York University Abu Dhabi in 2020 with a B. S. in Biology. She completed her undergraduate thesis in the Sadler Edepli Lab, where she studied fatty liver disease in zebrafish. Her research focused on how similar environmental conditions (both toxicological and microbiologic) can lead to differential disease outcomes. Her interests led her to pursue a PhD in the Microbiology and Environmental Toxicology program at University of California Santa Cruz where she joined the Kimmey Lab in 2021. Her research focuses on the regulation of innate effectors and pathogenesis.
