Professional Activities

I have been in position of various professional/academic activities. Some of them are listed below (in no particular order).

1. International Collegiate Programming Contest (ICPC)
   I have been the Regional Contest Director for Japan six times (2006 (unofficial RCD), 2018, 2019, 2020, 2021, 2022). I was also the 2007 ICPC World Finals Director. In most of the other years, I have been the coach of ICPC teams from Keio University, including the coach of the Keio team "Running" that went to the 2017 ICPC World Finals.  I am also currently a member of ICPC Japan Board, which oversees ICPC activities in Japan.   

2. CC2020 Steering Committee (and Task Force) member
   I was a member of the CC2020 project steering committee (and Task Force). This project was tasked to summarize and synthesize the various computing curricular guidelines, such as computer science, software engineering, and information systems. This project officially ended at the end of 2020. You can see the final report here.

3. Programming committee member
   I have served as PC member of various conferences, including ENASE (2024, 2025), IWSC 2023 (chair), FOSE(2003-2023), APSEC(2022, 2023, 2024, 2025), QUATIC(2022, 2023, 2024, 2025), MobileSoft(2023, 2022, 2021, 2018, 2017, 2016), IoECon2022,  ICST2021(Tool and Demos Track), WRSAT2020, Mobile!2016, SES(2016), 78th National Convention of IPSJ (PC vice-chair), DeMobile2015, MobileDeli2015, BICT2015 (MPSE Track), etc.

4. Other committee member
   I have served on various committees not listed above, including SES2024 Vice-Chair, AIQM (Artificial Intelligence Quality Management; 2020-), ICST2020 Publicity Co-Chair, JSSST Vice-Chair Board of Directors (2019-2020), JSSST Board of Directors (2016-2019), SamurAI Coding Organizing Committee (2013-2020), ICST2017 Student Volunteer Chair, 78th National Convention of IPSJ Organizing Committee Vice-Chair, etc.

Interested in joining my lab?

I am open to well-motivated international students (at both masters and doctoral level) who want to join my lab. If you want to join my lab, please contact me at michigan AT doi.ics.keio.ac.jp. Make sure that you specifically write why you are interested. Also, please note the following:

1. As a general rule, I do NOT accept short-term research student.

2. I cannot actually "accept" any students. That is done at the university level. For more information on applying to Keio University's International Graduate Program (IGP), please check the admissions WWW page. 

3. Japanese skill is not required to enter IGP. In fact, English is likely to be much more important.

4. I am sometimes very  busy, resulting in my response to be very slow.
