Sasha is currently researching and developing methods to produce lead perovskite (MAPbX3) crystals with different anions (X). She has already produced some bulk MAPbI3 crystals using different methods, and now she is working on substituting the iodide ion with other anions such as BF4-, PF6-. She is interested in this specific material for its photoelectric properties.  If you think this project sounds interesting and would like to work on a similar project, then contact Prof. Grimm to join now!

What brought you to WPI?

I came to WPI mainly because of its small community, which makes the professors really approachable for the students. I was also attracted by the fantastic projects program that allows me to apply what I learn to the real world before I step out of school.

What are your research interests?

I am interested in researching anything that could make the world a better place. Currently, my focus would be looking for ways to improve the efficiency of solar cells, so the solar resource could be better utilized by people.

What will you be doing immediately following your time at WPI?

After the BS/MS program at WPI, I will be going to a graduate school and pursue my PhD degree in material science (hopefully something related to what I am doing right now). I am planning on getting PhD degree in no longer than 10 years but it could also be 20 years since life is hard.

What are your long term professional goals?

Be a good engineer/ businesswoman that could contribute something to this world. Or at least not do the harms.
