Things I have been doing

Work History

Ono Laboratory, Tokyo Metropolitan University

October 2017 - Present

Postdoctoral Fellow — We use sound-to-light conversion sensors to easily build large sound sensing arrays. Applications are in conventional audio processing and large scale monitoring.

SAFECAST Japan

March 2011 - Present

bGeigie dude — Volunteer, designing, manufacturing and writing firmware for car-borne geo-tagged radiation measurement devices as part of a grass-root initiative to monitor fallout from the Fukushima Dai-ichi triple meltdown of March 2011. So far, 15 million measurement points have been collected using this system.

Audiovisual Communications Laboratory, EPFL

April 2017 - September 2017

Postdoctoral Researcher — Supervision of students. Prospecting data providers and participants for the Data Jam Days 2017 event at EPFL. Research and experiments in array audio processing.

Audiovisual Communications Laboratory, EPFL

September 2012 - March 2017

Research Assistant — Investigating how strucutral aspects of sound propagation, the echoes in a room for example, can provide more robust and efficient algorithms for problems such as beamforming, direction of arrival, or source separation. In a different line of work, I apply techniques from information theory and theoretical computer science to provide low-complexity algorithms for signal processing problems.

Media & Information Processing Laboratory, NEC Corporation

January 2011 - August 2012

Temporary Research Staff — Development of new algorithms for single-microphone speech denoising techniques based on spectral subtraction for application in consumer electronics. Specifically, speech harmonics preservation, DCT-based spectral subtraction, wind noise suppression.

Systems Software Group, IBM Research — Zürich

February 2009 - September 2010

Research Intern — Developed algorithms for the computation of the continuous Haar, Fourier and cosine transforms of rectilinear polygons found in IC layouts. Derived the theoretical computational complexity. Implemented the algorithms in a lithography tool and benchmarked against discrete transforms. Investigated the sparsity of the representation of the polygons in Haar basis and its application to the pattern analysis of IC layouts. Outcome resulted in scientific articles, highly optimized software and patents filing.

System IP Core Laboratory, NEC Corporation

March 2007 - January 2008

Research Intern — Implementation in Matlab of a 3GPP compliant simulator to evaluate the performance of different interference mitigation algorithms. Implementation and performance evaluation of QRD-RLS interference mitigation for Wideband CDMA on a CORDIC-based reconfigurable systolic array for software-defined radio (SDR) applications. The result of this work was presented at a domestic SDR conference in Nagano, Japan.
