CV
I am a third year PhD student at University of California, Berkeley in the EECS department. I finished my undergrad at Addis Ababa University, Ethiopia in Electrical and Computer Engineering. I am currently co-advised by Prof. Sarah Chasins and Prof. John Canny. I am part of PLAIT, CannyLab and BAIR.
My research interest broadly lies in the intersection of AI and HCI, with a focus on making usable AI tools accessible to end users. I am currently looking into making NLP tools usable and accessible for low-resourced languages. I am also interested in the impact of AI on society, specifically in how it affects Low Income Countries and people living in the Global South.
Outside of research, I like to read books📚, make and drink traditional Ethiopian coffee☕, knit🧣, explore art🎨, and write✍️.
News
I received the ACM-W scholarship to attend AfriCHI’23 where I will be presenting my work.
I built a library…not the code type…a physical library…where you find books :-). Read more about it here.
I will be TAing for Addis Coder in Summer 2023!!
Finally translated my website content to Amharic. More languages to come :-))
Was an invited speaker at the Wade Scholarship Program welcome event for 2022 Scholars.
Delighted to announce I am one of the 2022 winners of the SIGHPC Computational and Data Science Fellowship.
Excited to be featured with other Ethiopian women in STEM on BBC Amharic.
