Hi, nice to e-meet you! My name is Edwin Lim and I am currently a first-year Electrical and Computer Engineering PhD student working with James Hoe and Akshitha Sriraman at Carnegie Mellon University. My research interests lie at the intersection of computer systems and hardware, with a focus on making modern Machine Learning (ML) applications more efficient and sustainable. Specifically, my most recent research evaluates the potential of second-life GPUs and geographically distributed workload scheduling for more sustainable ML inference.

I completed my undergraduate studies in Electrical Engineering and Computer Science at UC Berkeley (Class of 2023), where I was fortunate to work with Sagar Karandikar and Krste Asanović on computer architecture research within the SLICE Lab. Here, I focused on enabling multi-FPGA accelerated simulation of large-scale RTL designs and building hardware (de)compression accelerators for hyperscale SoCs.

Currently, I am on leave from my PhD to work at… [TBD]

The best way to reach me is through email at eglim [at] andrew [dot] cmu [dot] edu.

Technical Interests

In general, I love working at the intersection of hardware and software to make things run quickly, efficiently, and scalably. In the distant past, I was primarily rooted in computer architecture, until I realized I have to write code in order for the chips I build to be useful (haha). The following topics, in particular, excite me greatly. The intersection of these fields is where I prefer to work.

• Computer architecture and systems
• Machine learning
• Sustainable computing
• Hyperscale systems

Non-Technical Interests

I’m a very active person, and am in the process of figuring out the whole “work-life-balance” thing. Having a life outside of work is critical to my sanity, but it’s easier said than done! Although I try not to fall into “Tech Bro” stereotypes, sometimes it is unavoidable. At least I do not currently own any Patagonia clothing (as of August 2024). Some of the things I do in my free time are:

• Rock climbing (I like bouldering)
• Weightlifting
• Hiking
• Biking
• Cello
• Super Smash Bros. Ultimate (I main Fox)
• Eating Korean/Indian/Japanese/Chinese/Mexican/Italian/Thai/Greek food (I’m not a fan of fusion though)
