Scott Karcher (Research Technician II) purchased his first home, and has been renovating/remodeling in his off time from the lab. Dr. Kate Schwetye was one of 10 pathologists to be recognized as Castle Connolly Top Doctors in 2023. The lab collectively brought in over 100 autopsy cases in 2022 and stained/performed IHC on 100 cases total for the year, which was a new lab record. We had a celebration to commemorate this achievement in April and pump ourselves up to complete over 100 in 2023. The lab has hired Ann Chaffee, PA (ASCP) into the THuNDR Lab. The Pathologist Assistant position is a new position within the lab and we are very excited to welcome a new staff member with a new skillset and experience to the team!

Randolph Research Laboratory

The Randolph Research Laboratory conducts research defining how transit cells and molecules out of tissues influences the inflammatory microenvironment. In this context, they focus on two chronic inflammatory disease settings, experimental atherosclerosis, and inflammatory bowel disease.

Ravichandran Research Laboratory

Every day, we turn over billions of cells as part of normal development and homeostasis. Majority of these cells die via caspase-dependent apoptosis. The prompt and efficient removal of these apoptotic cells is fundamentally important for our health. The recognition and phagocytic removal of these apoptotic cells occurs via the process of ‘efferocytosis’. Our laboratory addresses the molecules/mechanisms that regulate efferocytosis. This includes studying how apoptotic cells advertise their presence to phagocytes (‘find-me signal’ release), how phagocytes recognize and ingest the apoptotic cells (eat-me signals and phagocytic receptors), and how the phagocytes digest the ingested corpses. We are also interested in how the engulfment of apoptotic cells promotes immune tolerance (in contrast to other types of phagocytosis) and how this intersects and integrates with innate immune mechanisms. We use a combination of mammalian cell culture studies, knockout and transgenic mouse models, human samples, and genetic studies in model organisms.

Schreiber Research Laboratory

The Schreiber Research Laboratory is focused on elucidating the cellular and molecular underlying natural and therapeutically induced immune responses to developing and established cancers.

This group pioneered the use of immunogenomics approaches to rapidly identify immunogenic tumor-specific neoantigens and target them therapeutically.

Van Dyken Research Laboratory

The Van Dyken Research Laboratory studies how the immune system integrates diverse signals from the external environment and host tissues to maintain homeostasis and organ health.

Watson Research Laboratory

The Watson Research Laboratory is interested in identifying the genomic alterations that contribute to tumor cell metastasis in breast and lung cancer, with the goal of developing advanced genome-based diagnostics to detect, classify, and eradicate metastatic tumor cells to improve long-term patient outcomes.
