Professional activities

I recently joined Splunk working on Product Analytics. This page will be updated soon with more information.

I was previously a member of the Performance Team at Cloudera. My work involved both internal and competitive performance analysis and optimization. I specialized in performance across multiple components of our big data platform, including Hadoop MapReduce, Impala, HBase, Search, and Hive - someone had to make sure the entire Hadoop ecosystem runs fast together.

I'm a lead author to Statistical Workload Injector for MapReduce (SWIM), an open source tool that allows someone to synthesize and replay MapReduce production workloads. SWIM has become a standard MapReduce performance measurement tool used to certify many Cloudera partners. You can learn more about SWIM in our MASCOTS 2011 and VLDB 2012 papers.

I contributed to the first generation big data industry standard benchmarks within the Transactional Processing Council (TPC) - TPC-DS 2.0, TPCx-BigBench, TPCx-HS. I also serve as program committee member and reviewer to various conferences, publications, and NSF funding panels.

I hold a computer science PhD with MBA minor from UC Berkeley. My dissertation is Workload-Driven Design and Evaluation of Large Scale Data Centric Systems. I worked with Professor Randy Katz at the AMP Lab. My dissertation committee also included Professors Vern Paxson and Ray Larson.

Recent work

Non-technical interests

I am interested in how technology affects society at large. I believe we computer scientists should participate in relevant discussions and contribute our perspectives.

Half-presentable work from the past:

  • Gender Balance in UC Berkeley EECS. Y. Chen & J. Nam. 2007.

    Self-started research project. Results released in Spring 2007 to the Chair of EECS and the Diversity Director of the Department. Met with UC Berkeley Chancellor & the Assoc. Vice Provost for Faculty Equity to discuss results. Report forwarded to the Vice Chancellor for Equity and Inclusion, as well as other entities on campus.

Personal stuff

I was born in China, my whole family is in the United States, and I am technically an Australian. I hold interests unique to each country - I do Chinese caligraphy, I love college football (Go Bears!!!), and I still itch to play cricket. I went to an all-guys public high school in Australia, and apparently I still owe the teachers there some homework and beer and lost bets. I had a wonderful time as both undergrad and grad student at UC Berkeley. I'm working now, but I believe one should always be a student and constantly learning. My parents are chemists/chemical engineers, and taught me how not to have fun with chemicals. They live and work in New York. I used to play computer games a lot (most recently Civilization 4, Rome Total War, and Starcraft 2), I once was addicted to Friends, I'm reading the Game of Throne series and plan to re-read 100 Years of Solitude (didn't fully "get it" the first time but found it awesome), and I love Clint Eastwood and Al Pacino movies. I play tennis/badminton/table-tennis, I've made a home-recorded album for classical guitar and am halfway recording a second one, I hike sporadically, I've stopped doing archery regularly (not enough physical exertion), and I've lost $8 playing chess against homeless guys. Recently I've taken up fencing - initially did foil, now transitioned to epee (French grip, old school, I know). I'm currently focused on trying to lose more stylishly in fencing, but alway looking for the next hobby too. I hardly ever refuse to eat chocolate.

The rest to be filled later ...
