Christina

I am a 3rd year PhD student in computer science at MIT in the clinical machine learning group advised by David Sontag. I am interested in characterizing variation in how patients are treated, evaluating the effect of treatment policies, and handling dataset shift in predictive modeling.

I completed my MEng and BS in computer science at MIT in 2019. I interned at LinkedIn data science in summer 2021, Philips research in summer 2018, and IBM research in January 2018. I am grateful to have received the Abdul Latif Jameel fellowship for machine learning and health solutions for my first year of PhD. [CV]

I am passionate about welcoming new students to MIT. I am currently helping to build the EECS community as co-president of the EECS graduate student association. I focused on organizing visit days and orientation as co-vice president for 2 years. Before that, I led undergraduate orientation groups and advised first-year undergraduates.

I would be happy to hear from people at cji at mit dot edu or at my Twitter or LinkedIn!

If you are an MIT undergrad looking for a UROP in machine learning and healthcare, I am interested in working with you! Project description
