Osamu WatanabeDirector, Office of Research and Innovation
There are over 1,000 researchers at Tokyo Tech, and about one-third are researchers in their 30s and early 40s. It is my hope that industries will see the research emerging from our members' creativity and fresh perspectives, as well as the potential their research has in leading to new innovations. The purpose of the Research Festival is to introduce 30 researchers and their research topics. I believe that this Research Festival will be a wonderful opportunity for exchange and exploring possibilities.
Yasushi KawaseAssistant Professor, School of Engineering
We consider a problem of finding a stable matching between hospitals (or firms) and doctors (or workers) when budget constraints or type constraints are imposed on the hospitals (or firms). In such constrained situations, there may be no stable matching. In this research, we analyze the computational complexity for determining whether a stable matching exists and develop algorithms that find approximately stable matchings.
Makoto YamashitaAssociate Professor, School of Computing
The Yamashita research group employs a mathematical optimization approach to build a numerical method for various optimization problems in medicine including the "operation-room assignment," "beam intensity calculations for radiation therapy," and "effective reallocation of ambulances." We are also conducting research on how to formulate each practicall issue into optimization models.
Masao YamagishiAssistant Professor, School of Engineering
We focus on the "signal processing techniques that fully utilize optimization theory." Signal processing is a field to develop methods for extracting useful information from observations (images, time series data, and so on). In this research, we are studying a problem to extract the matrix caused by cyber attacks from the extended flow matrix (which expresses time transition of flow traffic and consists of privacy-aware information). For this problem, we propose its optimization problem formulation and the associated iterative solver, inspired by the robust principal component analysis.
Takashi IshidaAssociate Professor, School of Computing
"Deep learning" has been applied to fields such as image recognition with excellent results, and has now become an extremely important technology for analyzing life science data such as with proteins and DNA. We use special network structures including "3D convolutional neural networks" for data with a 3D structure known as protein cubic structure information to successfully improve prediction accuracy for issues such as "predicting 3D model accuracy estimations."
Shunsuke OnoAssociate Professor, School of Computing
We have been researching "techniques for effectively and efficiently estimating, processing, and analyzing desired information from sensing data containing noise, degradations, or missing information" by applying knowledge related to signal processing, mathematical optimization, and machine learning, which are fundamental data science technologies, across different fields. This time, we will introduce some representative research results generated in this process.

Yosuke MizunoAssistant Professor, Institute of Innovative Research
We have been developing a unique measurement technology that determines the strain and temperature distributions along optical fibers. In other words, we can measure where and how much strain (and/or temperature change) is applied to sensing fibers. We have recently achieved the world's highest spatial resolution and operating speed. First, we would like everyone in the industry to know the existence of such a technology. Then, we hope you will present some specific applications where this technology could contribute, and then find ways for joint development.
Makoto HagiwaraAssociate Professor, School of Engineering
Electric vehicles and electric railways use DC-DC converters, which are a type of semiconductor power converter. However, one problem is that the inductors used in these converters are large and heavy. For example, the weight/volume of an inductor for an electric railway can be as heavy as 1,000 kg. We are researching innovative DC-DC converters using the latest semiconductor power conversion technology (power electronics technology), and have discovered that it is possible to reduce the weight/volume of inductors to less than 1/50 that of conventional converters.
Safumi SuzukiAssociate Professor, School of Engineering
We are studying THz oscillators using resonant tunneling diodes, which are candidates for semiconductor device THz light sources, in order to realize various THz applications, and we have achieved operation up to 2 THz and milliwatt output at 1 THz, which are difficult using other devices. We are also tackling various THz applications such as wireless communication and spectroscopic analysis using developed devices, and have recently been strongly promoting research on THz radar.

Minho OAssistant Professor, School of Materials and Chemical Technology
About 30 million tons of waste concrete is generated each year, and it can only be recycled and used as roadbed material. High-strength, high-durability fiber reinforced concrete is difficult to recycle and is currently sent to final disposal sites. To realize a resource recycling society, it is essential that waste concrete be recycled. The purpose of this study is to focus on the recycling of fiber reinforced concrete and incorporate a resource separation and recovery process that takes advantage of the readily fusible nature (low melting point) of metal materials, which have been used in the nuclear energy field, in order to develop a fusible metal fiber reinforced concrete where the used raw materials can be separated and recycled.
Masaaki HirayamaAssociate Professor, School of Materials and Chemical Technology
We are developing material design methods based on analysis of solid-state electrochemical phenomena and searching for materials using various inorganic synthesis methods with the aim of improving the performance and adding new functions to power storage devices such as lithium-ion batteries and all-solid-state batteries.
Fumitake TakahashiAssociate Professor, School of Environment and Society
We are researching waste management and recycles from "upstream" where wastes are generated to "downstream" where wastes reach to the final disposal. What trash container design makes it easier to separate wastes? How boresome is it to separate wastes? How can additional value be created to encourage wates recycles? How much environmental risks are there in waste recycles and the final disposal? Will landfilled wastes be converted to soil? Focusing on waste, we are conducting interdisciplinary researches using psychological, chemical, mechanical, and mineralogical approaches.
Hiroyuki FujiokaAssociate Professor, School of Science
Materials around us are made up of atoms, and 99.95% of the mass of an tom is carried by the nucleus at the center of the atom. In other words, exploring the origin of a substance's mass is basically the same as unravelling the origin of the mass of protons and neutrons that comprise the nucleus. Theoretically, the structure of the vacuum surrounding a proton is considered to cause the proton to gain mass. We are planning an experiment using an particle accelerator to investigate the relationship between the vacuum structure and particle mass.
Hirotatsu WatanabeAssistant Professor, School of Engineering
Solid oxide fuel cells are power generation devices that promote the conversion of carbon resources (natural gas, coal, biomass, etc.) into high-efficiency energy.
However, since unwanted side reactions such as carbon deposition occur on the electrode surface, the reaction needs to be controlled.
The concept of my research is reaction design based on structural control of interface that form reaction sites with the aim of conducting a multi-scale investigation of surface reactions using first-principles calculations and observation techniques, and developing electrodes that have reaction selection functions.
Tetsuya KambeAssistant Professor, Institute of Innovative Research
We discovered a new two-dimensional boron nanosheet similar to borophen. This means we succeeded in synthesizing an atomic layer material consisting of boron and oxygen at normal pressure and in the air with the possibility of simple atomic delamination. As a new function, electrochemical characteristics were discovered, so we will report on this.
Toru HiraharaAssociate Professor, School of Science
The 2010 Nobel Prize in Physics was awarded for the creation of a two-dimensional planar sheet made of a single layer of carbon atoms called graphene, which was discovered in 2005, and the discovery of its quantum properties. Research on atomic layer materials exploded over the next 10 years. We are especially focusing on atomic layer materials that exhibit high-temperature superconductivity and topological properties. Our hope is that this will eventually lead to the production of quantum computers in the future using Majorana particles that are expected to appear in these systems.
Yuta NabaeAssistant Professor, School of Materials and Chemical Technology
Aromatic polymers such as polyimide and polyethersulfone have excellent thermal stability and chemical stability, but have rarely been used as catalysts.
I believe that the universal characteristics of aromatic polymers make them suitable as catalyst materials and their precursors, and am implementing themes such as (1) the development of new catalyst materials with aromatic hyperbranched polymer ends as catalytic sites, and (2) the development of carbon powder obtained by the carbonization of fine polyimide particles into a fuel cell catalyst.
Ken KomiyaAssistant Professor, School of Computing
Overturning the common idea of “manufacturing” with microfabrication using the DNA self-assembly that surpasses the microfabrication technology used in the semiconductor industry with a precision of 10 nm. It is possible to achieve ultra-precise and massively parallel microfabrication of 2 nm or less, exceeding the limits of conventional technology, without using expensive, large-scale manufacturing equipment. We will realize a dramatic improvement in efficiency, precision, and cost in various industrial fields from molecular production and energy conversion using enzymes to electronic device manufacturing, leading the way to a sustainable future.
Masayoshi TanakaAssistant Professor, School of Materials and Chemical Technology
Peptides are promising ligand molecules for various harmful and/or useful materials (e.g. TNT, virus, PM2.5, lipid and metallic particles) due to the abundance of variants derived from combinations of 20 natural amino acids with different physicochemical properties. By designing the amino acid sequence, we are now developing some techniques both for functional nanomaterial production by environmentally friendly course and for sensing of trace amounts of various targets.
