I am Apurba Kumar Barman, currently employed with R. P. Shaha University, Bangladesh as an assistant professor in the Pharmacy Department. As an assistant professor, I have experience developing and reviewing educational programs, teaching practical classes, and giving lectures for various courses. In addition, I have taken part in a variety of administrative tasks such as departmental program planning, student counseling, seminar organization, etc. In addition, I actively supervised the students' medication creation projects utilizing natural products. I have completed my Doctor of Philosophy Degree (Ph.D.) on Cell Biology at the Institute of Biophysics, CAS, China with the help of UCAS Scholarship, where my research was highlighted on the tumor recurrence mainly depends on lower CD8+ T cells/Tregs in the tumor microenvironment. Using PEG-PE micelle-based vaccinations in conjunction with radiation therapy to produce a robust immune response and long-lasting cure in mice with solid tumors has been the focus of my Ph.D. study. This work provides insight into the best times and orders to combine vaccination with radiation therapy to affect the tumor's immune microenvironment. Throughout my Ph.D. program, I have worked with a number of tools and approaches to better understand the interactions between cancer cells and their surrounding microenvironment, such as flow cytometry, advanced imaging, mRNA isolation, cell culture, and mouse cell inoculation. Prior to my PhD, I also joined the medicinal chemistry lab at the University of Zagreb, Croatia, as an exchange master's student sponsored by Experts4Asia Scholarship, where I explored the use of high-performance liquid chromatography (HPLC) to investigate CYP3A4 drug-drug interactions. My research aims to explore novel anti-cancer agents and clarify how cancer affects tumor growth. In order to enhance patient outcomes, I also want to ascertain the best time and mode of action for these inhibitors and apply my research into clinical settings.
