My recent work in the PIGI lab has focused on overcoming difficulties surrounding the generation of patient-derived models of primary liver cancer. This emphasis on improving cancer models stems from my conviction that therapeutic translation in cancer research could be greatly accelerated by increasing the availability of models that represent the diversity and complexity of human disease.

Alexey joined PIGI in the summer of 2019, during his research gap year while attending medical school in Tel Aviv. His background in Applied Immunology from University of Toronto enabled him to utilize his expertise to analyze hepatocellular carcinoma tumor microenvironment pre and post arterial embolic therapy. Now, as an IR/DR resident, he continues to be passionate about translational basic science.

Shurik is an aspiring actor who just took a very very short detour to get a BS in Physics from the University of Rochester, a 2 year introduction to translational imaging at Massachusetts General Hospital, and is now a graduate student in the PIGI lab (don't worry Hollywood, you'll get him eventually).

Bukola is awesome

I joined the PIGI lab in December 2018. In addition to being the lab manager, I am working with Daniel Ackerman to develop patient-derived models of hepatocellular carcinoma from biopsy samples to allow for functional precision medicine approaches.

After graduating from Swarthmore College and working at Memorial Sloan Kettering Cancer Center, Dan joined the lab in 2022 as a PhD student. He is focused on applying analytical chemistry methods to patient-derived HCC models, and developing robust pharmacokinetics, metabolomics, and mass spectrometry imaging methods is his passion (not graphic design). Outside of lab, Dan loves playing guitar, slow pitch softball, and hanging out with his cat, Mavi.

I have been working in PIGI Lab since February 2021 as Research Specialist. Before joining PIGI Lab, I have completed my Bachelor and Master of Pharmacy from Bangladesh then I completed MS in Pharmaceutical Science from Rowan University/CMSRU wherein my thesis was in preclinical drug development for treating neuropsychiatric disorder. I do have tremendous interest on drug discovery, more specifically pre-clinical drug discovery for treating cancer. There are chemotherapeutical drugs available and most of those are not capable of targeting only cancer cells. Scientists have been working on developing target based loco- regional therapy to treat specifically target tumor. One of the major ideas of PIGI Lab is to improve and develop new therapeutic methods to treat target tumor by minimally affecting non target cells which enticed me to learn and contribute to this pioneer research. My project in PIGI lab is working on rodent model to treat HCC by minimally invasive loco-regional therapy, known as trans-arterial embolization (TAE) with different particles, nano-particles, hydrogel often with the combination of traditional and novel anti-cancer drug molecules. In this project we regularly use T-2 weighted MRI, sometimes T-1 weighted MRI, ultrasound to stage tumor and image guided technology to precisely embolize the target tumor. We also analyze harvested tissue through IHC and other molecular techniques. Other than my lab- life, I enjoy workout, playing Cricket, and spend time in nature.
