Merging Nanotechnology & Synthetic Biology toward Directed Evolution of Energy Materials

The interface between nanomaterials and biological systems, the living and synthetic worlds, has evolved into a new science, nanobiotechnology, which deals with the design of materials for a variety of applications, from the environmentally friendly energy sources to neural modulation through optogenetics. The evolution of a new function, which goes far beyond the individual original inorganic particles and biological entities, requires a powerful combination of chemical synthesis, fabrication, synthetic biology, and self-assembly into hybrid hierarchical structures. In our work, we use microbial rhodopsins, transmembrane protein channels that are capable of light-guided translocation of ions across the lipid membrane. We demonstrated that by combining them with inorganic nanostructures they can function as artificial photosynthesis. Besides, by interfacing channelrhodopsin with XEOL nanoparticles we have developed wireless X-ray modulation of brain neurons.

CSE Career Fair

This is an opportunity to put a face to your resume and emphasize your strengths. Some students say their formal interviews are easier because they've already met the employer representative at the Career Fair and have established a rapport with the potential interviewer. Learn more at the Career Fair Home Page.

Dr. Siddharth Raju at the Wilson Lecture Series

A New Paradigm for Online Education and Research in "Power" Worldwide: Using ONR-funded Low-cost Rapid
Real-time Platform 

Compact and high-efficiency AC-AC power converters are crucial in grid integration of renewable and electrification of various sectors. Compared to existing ones, one of the leading contenders for a better AC-AC converter is the Matrix Converter (MC). This talk explores the research work to make these promising converters a more practically viable solution.

Research and education in power electronics, power systems, and drives, are limited to well-funded universities and companies. The major bottleneck is the exorbitant cost associated with the required software and laboratory infrastructure. As part of the Office of Naval Research funded project, a new code/model-based numerical simulation, and real-time prototyping platform was developed to make research and teaching in power fields more accessible. This talk explores the details of this research and its successful commercialization.

Biography of Dr. Raju

Dr. Siddharth Raju, is currently a researcher at the University of Minnesota. He received his Bachelor’s degree from SSN College, Anna University, India, in 2011, and his PhD in Electrical Engineering from the University of Minnesota in 2017. His research focuses on power electronics, electric drives, and real-time embedded controls. He is the co-author of the textbook on “Analysis and Control of Electric Drives” with Ned Mohan and 3 additional books in power electronics and renewable energy, to be published by Wiley.

Siddharth is the founder of Sciamble Corp., which was set up to commercialize his research work. The startup specializes in rapid real-time prototyping solutions. In a short period of two years since commercialization, his lab developments have been acquired by over 30 universities and companies worldwide, including well-known ones such as Texas A&M, Colorado State, MathWorks, and Semikron.

Susan Margulies, Ph.D., is an assistant director of the National Science Foundation, leading the Directorate for Engineering, and a professor in the Wallace H. Coulter Department of Biomedical Engineering, jointly housed in the College of Engineering at Georgia Institute of Technology and the School of Medicine at Emory University. She is Georgia Research Alliance Eminent Scholar in Injury Biomechanics and previously served as chair of the department.

Using an integrated biomechanics approach consisting of relevant animal models, cell and tissue experiments, and complementary computational models and human studies, Dr. Margulies’s research has generated new knowledge about the structural and functional responses of the brain and lung to their mechanical environment. Her lab has pioneered new methods for measuring functional effects of large or repeated tissue distortions; identified injury tolerances, response cascades, and causal signaling pathways; and translated these discoveries to preclinical therapeutic trials to mitigate and prevent brain and lung injuries in children and adults. Results are published in 185 peer-reviewed papers, including over 50 trainees.

Prof. Baris Taskin at the Wilson Lecture Series

Inter-Chiplet Synchronization of Multi-Die VLSI Systems

In VLSI systems, computing is projected to contain hundreds of components from heterogeneous processors, memories, and interconnect, in order to achieve performance gains and energy-efficiency in the face of increasing power-density. However, both hardware and software designers are faced with limitations in the improvement of instructions-per-cycle and clock frequency. As a result, designers have sought out heterogeneous computing devices, in system architecture and VLSI packaging, to accelerate current and future workloads.  At the VLSI packaging level, silicon interposer based heterogeneous integration of multi-die systems (MDS) has provided a new avenue for scaling of in-package computation, memory, and interconnects.

In this talk, I will focus on the synchronization subset of our efforts for silicon interposer based integration of VLSI multi-die systems (MDS).  In particular, I will present the solution our team has developed for inter-die synchronization in MDS that has a resonant clocking technology backbone. Resonant clocking technologies, which work on adiabatic, charge-recycling switching principles, generate very high frequency clock signals at a low power dissipation rate. In MDS, the presented implementation has a minimum footprint on the active interposer, which is important for yield and cost.  The proposed solution provides a centralized, synchronized and lightweight clock generation and delivery system that eliminates the need for PLLs and various clock/phase correction/synchronization overhead, which could especially be prohibitive for large scale MDS systems.  In addition to a superior synchronization profile, the proposed resonant clocking delivery leads to an average of ~40% total chiplet power savings (~72% on the clock network) in comparison to PLL-synchronized ARM Cortex M0-based 10mm by 12mm multi-core MDS simulation model.  At the end of this talk, I will also highlight two specific solutions our team developed for increased heterogeneity in architectures (and their efficiency) using resonant-clocking based inter-chipset synchronization,  where these architectures 1) demand frequency/voltage points distributed both spatially and temporally to achieve optimal performance, 2) require efficient I/O interface between chiplets.
