Two EECS projects awarded Berkeley Changemaker Technology Innovation Grants

CS Prof. Eric Paulos and Associate Prof. Bjoern Hartmann have both won 2020 Berkeley Changemaker Technology Innovation Grants to support projects involving "transformative ideas with real applications that  benefit the Berkeley campus."  Paulos's project is Lucid Learning, a suite of tools to help students in disciplines like architecture, art practice, theater, dance and performance studies, to incorporate augmented reality (AR) and virtual reality (VR) into their iterative processes of collaboration, design and feedback.  There are currently online tools that can help assess work in quantitative courses but few available for more open-ended, studio-based teamwork courses.  Hartmann's project, VRTutor, aims to both allow students to interact with an instructional 3D video pre-recorded by their professor in  VR, and also allow instructors to view a live feed of students working in VR to give them guidance.  Tutorial feedback can be offered by drawing on the student's video feed on a tablet, then re-projecting the drawings into the student’s VR scene in 3D.

Two projects led by EECS faculty win funding to combat COVID-19

Projects led by CS Prof. Jennifer Listgarten and EE Prof. Alberto Sangiovanni-Vincentelli have been awarded funding from the C3.ai Digital Transformation Institute to harness the power of AI to combat the spread of COVID-19 and other emerging diseases.  Listgarten's project will draw upon techniques such as reinforcement learning, robust uncertainty estimation and probabilistic modeling to develop new and trustworthy methods for therapeutic drug discovery for COVID-19.  Sangiovanni-Vincentelli's project will develop algorithms for AI that will help health care institutions better detect and contain emerging diseases.  These projects are two of six awarded to UC Berkeley, and among 26 projects world wide, which will share $5.4M to accelerate AI research for COVID-19 mitigation through advances in medicine, urban planning and public policy.

Introducing the world’s thinnest, most efficient, broadest band, flat lens

EECS Assoc. Prof. Boubacar Kanté, his graduate students Liyi Hsu, Jeongho Ha and Jun-Hee Park, postdoctoral researcher Abdoulaye Ndao, and Prof. Connie Chang-Hasnain, have demonstrated a revolutionary, ultrathin and compact, flat optical lens that spans wavelengths from the visible to the infrared with record-breaking efficiencies.  Their paper, “Octave bandwidth photonic fishnet-achromatic-metalens,” published in Nature Communications, is the first time a photonic system with the entire rainbow has been proposed and demonstrated with efficiencies larger than 70% in the visible-infrared region of the spectrum.  Attempts to make traditional lenses flatter and thinner, so that they can be deployed in increasingly smaller applications, have been hampered by the way that lens curvature and thickness are used to direct light.  The Fishnet-Achromatic-Metalens (FAM) utilizes a complex “fishnet” of tiny, connected waveguides with a gradient in dimensions, which focuses light on a single point on the other side of the lens, regardless of the incident wavelength.  As the world’s thinnest, most efficient, and broadest band, flat lens, its use in applications like solar energy, medical imaging, and virtual reality, is just the beginning.  As Kanté explains, “We have overcome what was regarded as a fundamental roadblock.”  One idea for a possible implementation would be to integrate the miniature lens into microrobots being developed at the Berkeley Sensor & Actuator Center (BSAC).

Tsu-Jae King Liu wins 2020 Chang-Lin Tien Award for Leadership in Education

EECS Prof. and dean of the College of Engineering Tsu-Jae King Liu has won the 2020 Chang-Lin Tien Leadership in Education Award.  The award honors an Asian American and Pacific Islander (AAPI) who has achieved "significant academic accomplishments and demonstrates the potential to advance to the highest leadership levels in higher education." Recipients are awarded $10K to establish a Chang-Lin Tien Scholarship Fund for AAPI students at their university.  The award was named in honor of Berkeley ME Prof. Chang-Lin Tien, who became the first AAPI to head a major US research university when he was elected Chancellor of UC Berkeley in 1990.  “This award is especially humbling to me," said King Liu, "because Dr. Tien was Chancellor when I joined the UC Berkeley faculty in 1996. I was touched by his warmth as a human being and affection for all things related to Berkeley, and am inspired by his example to advance the university’s noble mission of research, education, and service for the betterment of society.”

Aditya Parameswaran Awarded Best Paper at SIGMOD/PODS 2020

CS Assistant Prof. Aditya Parameswaran has been awarded the Best Paper Award at the 2020 ACM Special Interest Group on Management of Data (SIGMOD)/Symposium on Principles of Database Systems (PODS) for his joint paper: “ShapeSearch: A Flexible and Efficient System for Shape-based Exploration of Trendlines.”  The paper proposes the implementation of ShapeSearch, a tool that mitigates issues with existing visual analytics tools, such as limited flexibility, expressiveness, and scalability.  The paper was one of two that received the top award out of over 144 accepted research papers and 450 submissions to ACM SIGMOD/PODS, the premiere international conference on the theoretical aspects of database systems.

EECS researchers discover ferroelectricity at the atomic scale

A team of researchers led by EE Prof. Sayeef Salahuddin and his graduate student, Suraj Cheema, have managed to grow an ultra-thin material on silicon that can power tiny electronic devices at the atomic scale.  Prior to this fundamental breakthrough, the thinnest conventional material that could demonstrate stable ferroelectricity was 3 nanometers thick.  The new ultrathin material, made of doped hafnium oxide just 1 nanometer thick (equivalent to the size of two atomic building blocks), can demonstrate even stronger ferroelectricity than material several times thicker.  This means it can efficiently power increasingly smaller devices, including memory and logic chips, batteries and sensors, with lower amounts of energy.  The findings were published in the April 22 issue of Nature.
