Laboratory Members

Dannie Engle

Assistant Professor

Dannie received her B.A. from Northwestern University in Biology and Asian Studies and her Ph.D. in Biology from the University of California, San Diego in the laboratory of Dr. Geoff Wahl. She completed her dissertation work on the links between fetal mammary development and breast tumorigenesis. She then joined the laboratory of Dr. David Tuveson in Cambridge, England as a postdoctoral fellow before helping the lab relocate to Cold Spring Harbor Labs. As a postdoc, Dannie was part of a team of scientists who developed organoid culture technology for the propagation of normal, pre-malignant, and malignant mouse and human pancreas. Using organoid and genetically engineered mouse models, she later discovered a key role for the glycan CA19-9 in pancreatic disease pathogenesis. During her time as a postdoc, Dannie was the recipient of the K99/R00 Pathway to Independence award and the Theodore T. Puck award. Favorite Salt and Straw Flavor: Almond Brittle with Salted Ganache

Jan Lumibao

Postdoctoral Fellow

Jan Lumibao, Ph.D., obtained a B.S. in 2013 in Molecular and Cellular Biology from the University of Illinois at Urbana-Champaign, and a M.S. in Nutritional Sciences in 2015 from San Diego State University. In 2019, he graduated with a Ph.D. in Nutritional Sciences from the University of Illinois at Urbana-Champaign, studying redox-based mitochondrial mechanisms by which glioblastoma cells sense and respond to microenvironmental bioenergetic stressors. He joined the Engle lab in the summer of 2019 and is interested in understanding epigenetic mechanisms of glycosylation regulation in pancreas cancer. Jan enjoys running, cycling, hiking, and playing blues guitar. Favorite Salt & Straw Flavor: Peanut Butter Stout with Chocolate Chicharrón

Satoshi Ogawa

Postdoctoral Fellow

Satoshi Ogawa obtained his M.D. in 2009 from Kyoto University in Japan. After gaining experience as a gastroenterologist, he advanced to Kyoto University graduate school of Medicine. He studied pancreatic cancer using genetically engineered mouse models and the functional role of Histone modification in PDAC and received his Ph.D. in 2020. He joined the Engle lab in the spring of 2022 and is interested in understanding bile acid metabolism and glycosylation in pancreatic cancer. In his free time, Satoshi enjoys playing with his energetic kids and soccer with friends.

Jacob Tremblay

Postdoctoral Fellow

Jacob (Jake) Tremblay was born and raised in San Diego County (Poway). He obtained his B.S. in Cell and Molecular Biology from Point Loma Nazarene University in San Diego in 2012. He was awarded his PhD in 2018 from the Irell and Manella Graduate School of Biological Sciences at the City of Hope in Los Angeles County for his studies in adult pancreatic progenitor cell differentiation and self-renewal and pancreas development. Jake joined the Engle lab in the beginning of 2020 (pre-COVID) and now works on understanding the role of glycosylation in pancreatic cancer metastatic potential. Jake enjoys camping, board games, video games, everything fantasy/sci-fi, and forcibly sharing pictures of his cat Puma. Favorite Salt and Straw flavor: Tie between Cold Brew Coffee Cashew Praline and Chocolate Gooey Brownie

Herve Tiriac

Research Collaborator

Hervé received his B.S. in Genetics at UC Davis in 2005. During graduate school at UCSD, Hervé studied the regulatory networks coupling transcription and splicing in the laboratory of Tracy Johnson. After receiving his Ph.D. in 2011, he joined the laboratory of David Tuveson at the Cambridge Research Institute in the U.K. to study Pancreatic cancer and neuroendocrine tumors of the small intestine. In 2012, he helped relocate the laboratory to Cold Spring Harbor. There he optimized therapeutic and diagnostic platforms for patient-derived organoids. Hervé established robust methods to culture organoids from surgical tissue as well as fine-needle aspirates and core biopsies. Using an extensive library of organoids, he demonstrated that organoid pharmacotyping mirrors patient outcomes. Hervé is now an Assistant Research Scientist at UCSD in the Department of Surgery. He is establishing a research laboratory focused on patient modeling and precision medicine for pancreatic cancer. Favorite Salt and Straw Flavor: anything with pistachios or coffee.
Chelsea Bottomley

Chelsea Bottomley

Research Assistant

Chelsea received her B.S. in Animal Science with a minor in Biology from Cal Poly San Luis Obispo, where she acquired skills working in an animal nutrition lab. After graduation, she worked at after-school programs before moving on to the San Diego Zoo nutrition department for several years. She joined the Engle Lab at the end of 2021 in a dual position with the Evans Lab and is excited to learn new things and help advance cancer research. Chelsea enjoys playing games with family, losing hours doing genealogy, eating good food (but not cooking), and cuddling with her cats.

Alexandra Fowler

Research Assistant

Sasha completed her BS in biology in April 2020 at the University of California Riverside. While at UCR, she worked in an anatomy and physiology lab with mice, studying exercise, where she discovered her passion for scientific research. After graduation, she immediately joined the Engle lab as a Research Assistant. Sasha plans to pursue higher education and is currently debating between a Master’s in genetic counseling or a PhD in biology, with hopes to keep studying cancer. She also works with Make-A-Wish, helping cancer kids. In her free time, Sasha surfs, walks her dog, and tends her succulent garden.
