Jonathan Murata


Glad you could make it here today! My name is Jonathan Murata, but I go by Jon since most people (myself included) are too lazy to say the full thing. I just graduated with a Bachelors of Science in Electrical Engineering & Computer Science and Mechanical Engineering at the University of California, Berkeley. Yes, it's quite the mouthful every time I have to say it, so I usually just say I'm CS (haha).

If you're interested in learning more about me, you've come to the right place! Scroll down to see some cool stuff. If you just want an overview, this box should suffice! I was born and raised in Hawaii, but you probably couldn't tell given my poor pidgin and surfing skills. I'm currently living in Berkeley, CA and will soon move to South Bay to start a new chapter of my life working at Apple!

In the past year, a lot of my time has been devoted to teaching CS classes. In the little free time I have, I like to do the basics: eat good food and take long naps. When that gets a little too boring, I bake (mostly cookies), hang out with friends, play videogames, and think about how I should be coding or something instead of watching youtube videos.

Academics


My academic journey is really a story to tell. I graduated from the University of California, Berkeley studying Mechanical Engineering and Electrical Engineering & Computer Science. I didn't always have this long of an introduction, though; I started out as a MechE but eventually discovered the beauty of Computer Science. I became a part of the Berkeley CS community, taking hard courses, meeting great people, and even joining course staff as a TA for Data Structures, Machine Structures (Intro to Computer Architecture and low-level programming), and Operating Systems. In typical Berkeley MechE fashion, a chart is shown below to illustrate this (stressful) journey.

Red = non-tech, Green = general tech, Blue = Mechanical Engineering, Yellow = Electrical Engineering & Computer Science, Black = Teaching
Fa 2015 Sp 2016 Su 2016 Fa 2016 Sp 2017 Su 2017 Fa 2017 Sp 2018 Su 2018 Fa 2018 Sp 2019 Su 2019

Most Berkeley students use Berkeleytime to check enrollment and grade distributions. This process was pretty important through my college schedule planning, so I've included that data here mostly for nostalgic purposes (haha). The above chart was genearted with the distributions found on Berkeleytime for the semester I took the class, with my grade highlighted. As you can probably guess, this schedule was no walk in the park. Lots and lots of classes each semester :(.

Eventually I may return to graduate school, but I am putting that on hold for now. On the MechE side, my interests involve heat transfer and controls. I've done projects in biomechanics and heat transfer labs and briefly worked for a controls lab. On the EECS side, my interests involve systems, computer architecture, and parallel computing. I will be working in a Systems lab over the Summer.
