A better way to split ventilators

The COVID crisis has resulted in equipment shortages, including ventilators. Increasing ventilation capacity by sharing them between two or more patients is one option, but it has many risks. Dr. Lonnie Petersen, from the Jacobs School, and Dr. Sidney Merritt, from the School of Medicine, developed a process that would allow use of a ventilator to service two patients at the same time, addressing and solving key safety issues. The research has been accepted for publication by the journal Critical Care.

Real-time quantitative detection of protease activity
Patients with severe COVID-19 infections have higher levels of plasmin protease activity in their blood. This enzyme is thought to enhance the virulence and infectivity of SARS-CoV-2 virus by cleaving the viral spike protein. The UC San Diego team developed a sensor that can rapidly quantify protease activity in biological fluids. The new work appears in Nature Scientific Reports and is led by UC San Diego electrical engineering professor Drew Hall and UC San Diego Skaggs School of Pharmacy professor Anthony O’Donoghue. In their new assay, magnetic nanoparticles are immobilized to the surface of a giant magnetoresistive spin-valve sensor using peptides. Cleavage of these peptides by a target protease in a biofluid releases the magnetic nanoparticles resulting in a time-dependent change in the local magnetic field. The team has validated this assay to quantify proteases in urine and is currently modifying this assay to quantify plasmin in blood.

UCSD Privacy-preserving COVID-19 Contact Tracing Apps

Two teams in the Electrical and Computer Engineering (ECE) Department at UC San Diego are developing new cell phone applications for more accurate, private COVID-19 contact tracing. Led by electrical engineering faculty Dinesh Bharadia and Farinaz Koushanfar, the applications use wireless sensing and close integration with health systems, respectively, to monitor an infected person’s social interactions, while preserving the user’s privacy.

 

 UCSD & TU Darmstadt Privacy-preserving COVID-19 Bluetooth Contact Tracing App

Lead by Professor Farinaz Koushanfar

Prof. Koushanfar in collaboration with Technical University Darmstadt has developed  a novel privacy-preserving Bluetooth-based smart phone app for COVID-19 contact tracing. Contact tracing can be used to record and discover the social exposure of people with close contact to patients tested positive with COVID-19. The resulting app is aimed for integration within the UCSD myHealth website, which is based on the widely used Epic medical platform to perform contact tracing for patients and healthcare professionals. We are also working closely with Qualcomm on learning their Bluetooth measurement data and models for integration within our app. Koushanfar is tightly collaborating with the TU Darmstadt since they have successfully launched the beta testing of their tracing app. The tracing app complies to both privacy regulations of Germany and California.  To download the beta application go to https://tracecorona.net/download-tracecorona/

Meanwhie, BluBLE, an app under development in the Wireless Communications Sensing and Networking Laboratory, which is in the electrical engineering department, provides each user with a customized risk profile to determine their chances of contracting COVID-19. Now available on android and iOS, BluBLE uses infrastructure provided by Google and Apple to launch a novel algorithm that accounts for environmental context, including the exact distance between two people, their activity level (e.g. walking or jogging), whether the interaction took place in an indoor or outdoor environment, and the position of a person’s phone. All of this information is gathered while keeping each user anonymous.

Using voice to detect COVID-19

Researchers at UC San Diego are part of a collaborative, multinational effort to use changes in voice to detect COVID-19. They are gathering voice and coughing audio samples from people who both have and have not tested positive for COVID-19. Then, researchers including those at UC San Diego, are using algorithms and neural networks to pick out differences in the patterns between the two groups, with a goal of being able to detect if someone has the virus simply by them speaking or coughing into their phone or computer microphone. Computer scientists, electrical engineers and mechanical engineers at the Jacobs School are contributing to the analysis of open source data collected by several different companies and institutions, including Voca.ai, Vocalis, Carnegie Mellon University and MIT.  

Shlomo Dubnov, a professor in the Departments of Music and Computer Science and Engineering, is leading UC San Diego’s involvement in the project, and is using tools he and his lab developed to analyze musical sounds. UC San Diego researchers, including mechanical engineering graduate student Tammuz Dubnov and his startup company Zuzor, are also developing and repurposing tools to be able to deploy these detection algorithms over apps and web browsers.

UV-Drone: Mobile Disinfection Platform for Community Facilities with Minimum Human Exposure

Disinfecting areas that have been exposed to COVID-19 using conventional methods of washing and cleaning surfaces with disinfecting liquid and materials, exposes the most disadvantaged workers on the frontlines and increases the risk of exposure and disease contraction for the cleaning crew. Professor Tara Javidi is leveraging her DetecDrone research platform developed at UC San Diego to significantly improve on the process of UV-based disinfection. In addition to providing a cost effective and agile non-contact UV-C sterilization, the researchers envision the first Do It Yourself (DIY) prototype of a drone platform for delivering non-contact mobile UV sterilization unit (UVerizeDrone) for community facilities such as schools, institutions of higher education, offices, daycare centers, businesses and community centers. Javidi is Co-Director of the Center for Machine-Integrated Computing and Security (MICS) at the UC San Diego Jacobs School of Engineering. Learn more on the MICS COVID-19 page.

 

UC San Diego Team Delivers Protective Equipment to Hospitals in Baja California

The COVID-19 pandemic is impacting the availability of personal protective equipment (PPE) supplies in Baja California, and researchers with UC San Diego are engineering solutions to help. Nadir Weibel, an associate professor in the Department of Computer Science and Engineering and head of the Human-Centered and Ubiquitous Computing Lab, is collaborating with university colleagues, government and industry to develop PPE solutions and to transport ing supplies, like masks and face shields, to hospitals in Baja.

So far, the team in collaboration with the CAICE lab and the Scripps Institution of Oceanography has produced, tested and delivered 3,000 face shields, with around 1,100 masks on the way. The protocols to make this equipment have been published on Earth 2.0, a curated clearinghouse started by UC San Diego faculty and students for COVID-19 information and solutions.

Researchers Awarded NSF Grant to Apply Epidemic Model to COVID-19

Behrouz Touri and Massimo Franceschetti, both on faculty in the Department of Electrical and Computer Engineering Department at UC San Diego, have secured funding from the National Science Foundation to address COVID-19 using the Susceptible Infectious Recovered (SIR) mathematical model. The two researchers are in the early stages of adapting the SIR model to the current pandemic, in the hopes of identifying policies that effectively reduce the number of COVID-19 infections and mortalities, while limiting the cost to the economy. In time, the researchers hope to provide officials and policymakers at the city and regional level with insight into the efficacy of social distancing, stay-at-home orders and other guidelines.

Privacy-preserving COVID-19 Discovery

Several research labs worldwide, both on the industrial and university side, are focused on sequencing the COVID-19 virus and studying its interactions in-vivo and in-vitro. In several cases, sharing the data and models is not possible due to privacy and IP issues, impeding collaboration for achieving a faster discovery. Professor Farinaz Koushanfar’s lab provides one-of-a-kind provable privacy-preserving methodologies, based on verified cryptographic protocols, which enable collaboration among the various entities in an encrypted domain. With this method, the privacy of the IP/content owners is not compromised, while new collaborations and discoveries are uniquely enabled. In particular, multiple research labs will be able to jointly work on the encrypted version of the aggregated data without disclosing their sensitive information to any other research lab. These state-of-the-art technologies provide a secure platform such that the confidentiality of the data during computation is guaranteed. The platform also assured the correctness of the computation; the result is equivalent to running the underlying algorithm on the cleartext (unencrypted) data. The platform will remove several critical obstacles in the global-scale study of COVID-19, and in turn, will accelerate the process of finding new recovery mechanisms. Koushanfar is Co-Director of the Center for Machine-Integrated Computing and Security (MICS) at the UC San Diego Jacobs School of Engineering. Learn more on the MICS COVID-19 page.

Robust AI for Automated and Accelerated Literature and Trend COVID-19 Systemization of Knowledge

Professor Farinaz Koushanfar is leading development of novel robust and safe accelerated methodologies, based on natural language processing (NLP) to systemize knowledge discovery in the COVID-19 domain. While several disparate entities are working in research on the topic, and a multitude of sources are publishing news on a daily basis, their platform is interactive, allowing researchers and public health professionals to follow the many updates. NLP-based methods are useful for automated knowledge discovery but suffer from the existence of unreliable sources, data poisoning and fake news. This effort focuses on making the automated knowledge search systematic, safe and robust, while we simultaneously address scalability through new hardware/software/algorithm co-design. Koushanfar is Co-Director of the Center for Machine-Integrated Computing and Security (MICS) at the UC San Diego Jacobs School of Engineering. Learn more on the MICS COVID-19 page.

A Controlled Response to COVID-19

Electrical engineering rofessors Massimo Franceschetti and Behrouz Touri are proposing a generalization of Susceptible Infectious Recovered (SIR) model for inhomogeneous population. Using tools from optimal control and nonlinear control and based on the proposed mean-field model, they are working to find the optimal-cost containment policy to meet the local health-care provider's care capacity.

A team of engineers and physicians who developed the device are hoping it will be able to detect respiratory and cardiac changes that occur before patients develop COVID-19 related pneumonia. Hundreds of devices have been manufactured and they are currently in patients’ homes throughout San Diego County. The effort is led by bioengineering professor Dr. Kevin King, who is also a practicing cardiologist with UC San Diego Health, and bioengineering professor Todd Coleman.

COVID-19 sequencing analysis in real time
Bioinformatics researcher (and computer science teaching professor) Niema Moshiri created an automated tool that analyzes in real time genomic coronavirus open-source datasets from the Global Initiative on Sharing All Influenza Data (GISAID).  The tool outputs results in a way that is more user-friendly for public health and biology researchers. Some of the information that can be extracted from analysis includes the virus' most likely evolutionary history; information about the common ancestors of viral samples; and information about how recent each version of the virus is in given clusters of patients. This could help health officials determine effective policies to contain the virus and to potentially design therapeutics. Moshiri received a $200,000 RAPID grant from the National Science Foundation for the work, with computer science professor Tajana Rosing. The tool can be found here on Github.  Read Moshiri's related article in The Conversation, which also appeared in many US newspapers, including the San Francisco Chronicle
