Mekhail Anwar is an affilated BSAC faculty member and Associate Professor in Residence in the Radiation Oncology Department at UCSF, with an affiliate appointment in our department. Professor Anwar's research areas include many areas within the broad area of electronic circuits and devices.


Dr. Anwar's goal is to solve the fundamental and persistent challenge in cancer – identifying where all tumor cells are and how patients respond to treatment – opening the door to truly precision, personalized medicine. I develop imaging and biosensing tools using...

CMOS image sensors have been widely used for decades, largely displacing CCDtechnology in cameras, scanners, telescopes, and a variety of medical sensors. Photodiodes are formed in the IC substrate and the technology has been repurposed to make more advanced structures with higher sensitivity, such as pinned or avalanche photodiodes. Less work has gone into generating optical elements using other features of the CMOS process, namely the metal interconnect. The precision deposition and spacing of the metal...

BPN685: Real-Time Intraoperative Fluorescence Imager for Microscopic Residual Tumor in Breast Cancer

Successful treatment of early stage cancer depends on the ability to resect both gross and microscopic disease, yet no method exists to identify residual cancer cells intraoperatively. This is particularly problematic in breast cancer, where microscopic residual disease can double the rate of cancer returning, from 15% to 30% over 15 years, affecting a striking 37,500 U.S. women annually. Currently, residual disease can only be identified by examining excised tumors under a microscope, visualizing tumor cells stained with specific tumor markers. This microscopic evaluation restricts...

BPN882: An Ultra-Thin Molecular Imaging Skin for Intraoperative Cancer Detection Using Time-Resolved CMOS Sensors

Successful treatment of cancer requires targeted and individualized treatment, and subsequently an assessment of the state of the tumor being examined, both gross and microscopic, however oncologists have no method of identifying microscopic tumor in the patient. This results in tumor cells being left behind in patients undergoing surgery. Currently, the only way to determine the presence of any microscopic residual is to examine the excised tumor, stained with a proper marker, under a microscope, which only adds to the complexity and length of the surgery and treatment. The two current...

Ultrasonic 3D Rangefinder on a Chip

Optical 3D imagers for gesture recognition, such as Microsoft Kinect, suffer from large size and high power consumption. Their performance depends on ambient illumination and they generally cannot operate in sunlight. These factors have prevented widespread adoption of gesture interfaces in energy- and volume-limited environments such as tablets and smartphones. Gesture recognition using sound is an attractive candidate to overcome these difficulties because of the potential for chip-scale solution size, low power consumption, and ambient light insensitivity.

Our research focuses...

BSAC Seminar: Circular Orbit Operating Mode for MEMS Gyroscopes

Mitchell H. Kline Electrical Engineering and Computer Sciences, UC Berkeley BSAC Graduate Student Researcher August 28, 2012 | 12:00 to 12:30 | 540 Cory Hall, DOP Center Conference Room Host: Bernhard Boser

We present a gyroscope operating mode that reduces bias errors and scale factor drift and allows whole angle read-out. The gyroscope proof mass orbits in a circle at its natural frequency. An outside observer rotating under the proof mass then perceives a frequency change. If the observer rotates in the same...

Frequency Modulated Gyroscopes

2013

MEMS gyroscopes for consumer devices, such as smartphones and tablets, suffer from high power consumption and drift which precludes their use in inertial navi- gation applications. Conventional MEMS gyroscopes detect Coriolis force through measurement of very small displacements on a sense axis, which requires low-noise, and consequently high-power, electronics. The sensitivity of the gyroscope is im- proved through mode-matching, but this introduces many other problems, such as low bandwidth and unreliable scale factor. Additionally, the conventional Coriolis force detection method...
