I am Tatiana, a PhD student at Johns Hopkins University from Russia. My background is in engineering, nuclear physics, nuclear reactors, modeling and simulation, and computer science.  In my dissertation, I work on radiotherapy treatment response assessment and prognosis of metastatic brain cancer. I am also interested in medical physics, environmental health, and the development of non-animal research computer models. This portfolio contains some stories about my childhood, early educational journey, and past research and social activities. After finishing my PhD, I plan to contribute to cancer patient care as a medical physicist and scientist for some time. Then, I will devote the rest of my life to charity and service work for poor people, animals, and the environment because, to me, life is about love.
