Prof Chang, Joseph SylvesterJoseph Chang is multi-disciplinary engineer with research encompassing core CAS-related fields including analog, digital and aerospace circuits/systems; biomedical/life-sciences related-fields; and the emerging printed-electronics. He received the B.Eng (ECE) from Monash University, and Ph.D. from the Department of Otolaryngology, Faculty of Medicine, University of Melbourne, and has two-years IC-related industrial-experience. He is currently with the Nanyang Technological University, Singapore (and Adjunct at Texas A&M). He has contributed to senior university administration and to ECE undergraduate/graduate education. He was the inaugural Associate-Dean of Research-and-Graduate-Studies at the 660 faculty-strong College-of-Engineering. For undergraduate education, he emphasized on promoting and instilling undergraduates’ interest in ECE, including being the chair of the Undergraduate-Research-Experience-on-Campus and Undergraduate-Research-Opportunities-Program programs, chaired Orientation-Programs and national-level undergraduate-conferences, and has given several talks in high-schools. In the IEEE, he contributed to both core and multi-disciplinary fields, including as Guest-Editor of the Proceedings-of-the-IEEE on ‘Computational System-Biology’, Guest-Editor of the CAS-Magazine on ‘Special-Issue on Life-Sciences’, Editor of the CAS-Magazine’s Open-Column, Chairperson of the IEEE-NIH Life-Sciences-Systems-and-Applications (LiSSA) Workshop, Chairperson of two IEEE-NIH CAS-Medical-and-Environmental (CASME) Workshops, Chairperson of the LiSSA Technical-Committee, Associate-Editor of IEEE TCAS-I (3-terms) and -II, Associate-Editor of the IEEE CAS-Magazine, Distinguished-Lecturer, etc. Of specific interest, he organized the successful merging of the BioCAS and LiSSA technical-committees, largely for CAS’s concerted/united life-sciences efforts. He was instrumental in several non-IEEE establishments’ engagement in CAS’s activities, including other IEEE societies, National-Institutes-of-Health, Telemedicine-and-Advanced-Technology-Research-Center, American-Institute-of-Medical-and-Bioengineering, etc. Impact thereto includes NIH’s request for each of their 27 institutes a copy of the aforesaid CAS-magazine’s special-issue, representation by different IEEE societies at the IEEE-NIH workshops and NIH financial support for CASME. He has published over 200 referee-reviewed publications (primarily in IEEE) and has over 20 patents (awarded/pending). In the field of ‘Class-D amplifier’, he has the most number of publications in the IEEE; and the top-ranked paper (excluding patents) and four of the top six papers in ‘Digital Class-D Amplifier’ in Google Scholar. He has received numerous grants from local and international funding-agencies (including DARPA and the EU) and from industry, amounting to >US$10M. He has founded two startups, and has designed numerous ECE-related products for industry.

Prof Denis FichouOur present research aims at conceiving novel materials, either organic or inorganic in nature, in view of energy applications such as sunlight conversion and storage. 1. Organic and hybrid photovoltaic cells We design and synthetize novel small organic molecules having an extended pi-electron system and use them either as active materials (p- or n-type semiconductors) or as interfacial layers in thin film solar cells. We recently developed series of molecules such as for example dipyrranylidenes and organo-cobalt complexes, that we used to fabricate efficient photovoltaic solar cells. 2. Oxide-based photoelectrochemical systems We aim at converting efficiently sunlight into clean and readily usable fuels such as hydrogen or methane on a large scale. One of the most promising technologies consists in splitting water into hydrogen and oxygen through solar irradiation of semiconductor-based devices. We recently designed various efficient PEC systems based on either WO3, Cu2O, or BiVO4 among others, and used them under sunlight illumination to produce hydrogen. 3. Supramolecular self-assemblies on surfaces The self-assembly of organic molecules on solid surfaces provides a versatile route towards functional 2D arrays in view of energy, catalytic and magnetic applications. Our group develops unique supramolecular architectures by controlling the size and shape of the molecular bricks. We then observe and manipulate the assemblies at the atomic/molecular scale by means of scanning tunneling microscopy (STM).
