Hi! I’m Ajay and I’m a fourth year computer science major from the Silicon Valley. In my free time I like playing basketball, listening to old music, and driving around the bay.

Hello! My name is Alex Schedel and this is my 8th time teaching 61B! I have been teaching this class so long that I used to teach it in person and I am really looking forward to getting to do that again. I am a double major in both Film and Computer Science, so if you want me to inform you as to exactly why Stalker is probably the greatest film of all time and why the Dark Knight is as overrated watching the ball drop on New Years Eve all you have to do is ask.

Helloooo data structures lovers of the world. I'm a senior EECS major and I'm here to PARTY (in a strictly educational sense). I've taught twice as a TA and once as instructor, and I'm excited for the best semester of 61B yet! In my free time I like to knit, blow a lot of money on thai food, and curate really specific playlists! I'm pretty sure I'm supposed to link a "professional website" or something but I'm linking my Spotify xoxo

Hi everyone! I'm a senior majoring in computer science and linguistics. I love everything to do with language - how it's formed, how it's structured, the list goes on. Currently, I do research on natural language processing (think Siri or Google Translate) on low-resource languages and non-standard dialects. When I'm not working, I like to play animal crossing, bake cakes, and explore new restaurants.
