Lab Members

Yoko NishigaPostdoctoral Fellow 

Yoko Nishiga received her MD from Kyoto University in 2007, and worked at Aichi Cancer Center Hospital as a radiation oncologist. She received her PhD from Kyoto University Graduate School of Medicine in 2015. Her research was focused on tumor microenvironment, especially focused on tumor hypoxia and radioresistance. She joined the Ted lab as a postdoctoral fellow in Nov 2017. She is interested in how radiotherapy affects immune cells and tumor microenvironment and how to overcome the radioresistance of tumor and improve the prognosis of cancer patients.

Saravanan NandagopalPostdoctoral Fellow

Saravanan received his Bachelor degree in Pharmaceutical Sciences and he is a registered pharmacist from India, and later obtained his Master’s degree in Biochemical Engineering from the Banaras Hindu University. He enjoyed and survived the harsh winter in Winnipeg, Manitoba to obtain his Doctoral degree on T-cell migration in lymph node relevant chemokine fields using microfluidic devices from the University of Manitoba, Canada. Getting interested on immune cell migration, he focused his post-doctoral research on NK cell migration relevant to tumor microenvironment at the department of Immunology, University of Manitoba for two years. Moving south to California to enjoy the warmer weather to investigate the immune cell interactions in tumor microenvironment. In his free time, he enjoys cooking with his family, enjoying Ilayaraja’s tamil melodies and watching cricket.

Luis Soto, Graduate Student

Luis grew up in the Bay Area after moving to California from Peru with his parents when he was twelve. He earned his B.S. and M.S. in Cell and Molecular Biology in 2011 and 2014, respectively, from San Francisco State University. He joined Stanford University as a PhD student in the Cancer Biology program in 2014. Luis is interested in studying the role that immune cells play in mediating tumor survival, especially in identifying the molecular mechanisms that promote resistance to radiation therapy. When not in lab, Luis likes to play soccer, hang out with friends, and go camping.

Stavros MelemenidisPostdoctoral Fellow 

Stav is a Physicist in training (B.Sc. in Physics with Medical Applications) with expertise in radiation detection (M.Sc. in Radiometrics: Instrumentation and Modelling) and radiation biology (M.Sc. in Radiation Biology). He joined the Graves lab after completing his Ph.D. in Radiation Biology from Oxford University, at the Experimental Neuroimaging Group, where he focused on the development of novel molecular contrast agents for in vivo imaging methods, aiming to monitor angiogenesis in solid tumours or early detection of pulmonary micrometastasis. During his research in Stanford, Stav aims to expand his expertise in Radiation Therapy and more specifically on the effect of radiation in healthy cells and tumour cell migration. Outside work Stav is a passionate capoeirista (Capoeira Angola), a good friend and a wannabe philosopher. 

Yasaman Ahrari, Research Assistant

Yasaman received her BA in Art History from Bard College in New York. She had an interest in attending school for dentistry, thus she pursued fulfilling prerequisites for dental school alongside her art history studies. After considering many careers in the healthcare field, she was introduced to radiologic technology and is now aiming to continue her studies in this field. She was fortunate enough to start an internship at the Graves lab to broaden her knowledge of research in radiology and its applications in the early detection of cancer. Yasaman takes classes and occasionally works with her mom, who owns a daycare. 

Jon Wang, Undergraduate

Jon is a current undergraduate studying Computational Biology interested about the role macrophages play in tumor recurrence following radiotherapy. To investigate this, he is varying macrophage content and recruitment mechanisms and analyzing the effect this has on post-irradiation tumor cell recruitment and macrophage distribution. This research may shed light on the mechanisms behind radiation therapy and tumor recurrence, with the potential of providing more effective post-radiotherapy treatments. Outside of research, he is involved in a number of health-related initiatives on campus including Stanford's EMS, Healthcare Consulting Group, and ImpactMed. During his spare time he's a violinist in chamber music, goes to the gym, and plays card games! He's excited to learn more about the research process, and ways he can apply the knowledge he learns in classes toward clinical solutions.

Annie Xu, HS Summer Intern

Annie is a rising senior at Saratoga High School. This is her first delve into either oncology or radiology, but overall her interests lie in biology and environmental science and engineering. In her free time, she dances and runs her school's environmental club. This summer she will also be performing in a youth production of the musical Annie and, backstage, sadly be writing her college apps.
