+    Hi, I’m Alex, a PhD student and tutor in Computer Science. This year I’m president of Warwick AI, and I previously led the Projects department. My research focuses on variational autoencoders. I'm also involved in the department research on the use of AI in higher education and have an interest in using diffusion models to create art (I will also run a workshop on creating AI art!!!).

+    Hi everyone, I’m Sam, a second year Computer Science student from Coventry, and Warwick AI’s Vice President this year! Within AI, I’m mostly interested in how AI can be used with simulations to help solve problems in the natural sciences. Outside of AI, I enjoy climbing and can play the flute! Fun fact: I have a 1,200 day streak on Duolingo!

+    Hi Everyone, I'm Laura, a 2nd Year PhD Student. My field of research is learning dynamics of neural networks and implicit bias of optimisers. If none of that made any sense to you (or if it did), come chat to me about it! I'm WAI's head of education this year, so you can find me at WAI's courses or codenights and quiz me on all things AI. I look forward to meeting you all!

+    Hey! I'm Tara, a 2nd year Discrete Maths student, and I'm your Projects Officer for 25/26! The drone project was what brought me to the society last year, and projects I feel is what makes this society what it is! AI-wise, I've mainly worked with OpenCV & visual processing, both with the drone project and my own climbing app. Hobby-wise, I climb too much, go to too many societies, speak French to myself, and am too emotionally attached to my bicycle :D
