Student Spotlight Interview with Michael Collins September 28, 2015

Congratulations to Michael Collins, who graduated from Northeastern University in August 2014 with his MS in Electrical and Computer Engineering, as he is preparing to complete his participation in the ALERT DHS HS-STEM (Homeland Security Science, Technology, Engineering, and Mathematics) Career Development Program!

The Career Development Program (CDP) was established in 2011 with a grant to Northeastern University from the Department of Homeland Security, Science and Technology Directorate. In 2015 the program was expanded and renamed, and now awards fellowships to full-time students pursuing BS, MS or PhD degrees related to ALERT’s research. After completing their degree and other program requirements, graduates are required to obtain paid employment within the Homeland Security Enterprise for at least one year.

During his time at Northeastern, Michael worked with Prof. Carey Rappaport on a project focused on the feasibility of using Nuclear Quadrupole Resonance sensing for non-invasive detection of explosives hidden inside the body, in collaboration with Los Alamos National Laboratory.

Of his experience working with Prof. Rappaport, Michael says that, “having a great advisor makes all the difference in a research program. Professor Rappaport’s many insights and patient explanations taught me things that are hard to learn any other way.” As part of the CDP, Michael participated in a 10-week long internship with Los Alamos National Lab, and recalls the opportunity to visit New Mexico to collect data for his thesis as being one of the highlights of the program.

Now, Michael is working at the Centre for Maritime Research and Experimentation (CMRE) a NATO organization located in La Spezia, Italy. He began his search for Homeland Security Enterprise positions after graduation in August, 2014, and received his offer to start at CMRE in October, 2014. Michael was initially drawn to the Centre’s research on autonomous underwater vehicles (AUVs) for port security, anti-submarine warfare, and mine detection. So far, he has worked on technology that improves underwater communication, performed acoustic modeling, and has participated in a naval exercise in Norway. Of his current role, Michael says, “I am now in charge of a project that reduces the risk faced by submariners. Like the research that I conducted at ALERT, it’s good to know that my current work makes people safer.”

When asked to reflect on his experience working with Michael, Prof. Rappaport describes him as “an incredibly hard worker: when he sets his sights on a goal, no matter how ambitious or distant, he will attain it through sheer force of will. It’s great to see him succeed in this high responsibility job.”

TESSA02 Workshop Announced July 1, 2015

ALERT is pleased to announce it will be hosting the Second “Trace Explosives Sampling for Security Applications” (TESSA02) Workshop, which will be held on August 5th, 2015 at Northeastern University in Boston, MA. The title of the workshop will be “Fundamentals and Advances in Trace Sampling and Detection.” The TESSA02 Workshop, held in 2014, was the first in the series to deal with the development of a roadmap for understanding contact sampling for trace explosives detection. The topic of contact sampling was chosen for the workshop in order to support the Department of Homeland Security’s (DHS) objective of improving the performance of existing technologies.

ALERT Research Featured in The New York Times July 1, 2015

ALERT “Tag-and-Track” video surveillance research was featured in a recent New York Times article, which discussed the video analytics project being led by Prof. Octavia Camps and Prof. Mario Sznaier at Northeastern University.

The software developed by Profs. Camps and Sznaier, along with their fellow researchers and students, uses airport security cameras to detect suspicious behavior by passengers. The article makes note of the high success rate and capabilities of the software, as it is currently in use at the Cleveland Hopkins International Airport to detect passengers who try to enter secure areas of the airport through an exit lane.

ALERT Continues to Foster Collaboration at ADSA12 Workshop July 1, 2015

On May 12-13, 2015, the Twelfth Advanced Development for Security Applications Workshop (ADSA12) was held at Northeastern University in Boston, MA. The workshop focus was, “Screening of Personnel and Divested Items at the Checkpoint,” and was a continuation of the first workshop, ADSA01. The topic was chosen in order to support the Department of Homeland Security’s (DHS) objective of improving the performance of existing technologies and to improve the passenger experience at checkpoints. Another goal of the workshop was to support DHS’s objective to increase the participation of third parties, such as researchers from academia, national labs, and industry other than the incumbent vendors, in algorithm and system development for security applications.

The following topics were addressed at the workshop: emerging hardware; emerging algorithms and processes; improving the passenger experience and assessing and using risk. The topics were addressed from the perspectives of the TSA, airlines, and passengers.

The key findings from the workshop on what can be done to solve the checkpoint problems are: use of risk based screening including under-screening; improved concept of operations; integrating systems and data; setting standards for systems interfacing, data integration and testing in lab and field; developing better hardware and reconstruction software and identifying orthogonal technologies.

The next workshop, ADSA13, is scheduled for the fall of 2015, will be a continuation of ADSA12 and will concentrate on the following topics: trace and standoff detection; video analytics; application to mass transit and federal buildings; fusing orthogonal technologies; explosive threats; networking; laboratory and red-team testing; third party development of Automated Threat Recognition and reconstruction algorithms; machine learning; prevalence shifting; (trading off Probability of Detection for Probability of False Alarm); concept of operations; measuring and using risk; deterrence; and case studies.

Student Spotlight Interview with Mihindra Dunuwille July 1, 2015

Congratulations to Mihindra Dunuwille, a spring 2015 Chemistry Ph.D. graduate at Washington State University (WSU), who has recently started working as a postdoc at the University of Utah! During her time at WSU, Mihindra worked on ALERT research under the guidance of Prof. Choong-Shik Yoo. Her thesis, “Pressure-induced Physical and Chemical Changes of Non-conventional Energetic Materials: Nitrate, Perchlorate and Peroxide Chemistries at High Pressures and High Temperatures,” focused on discerning the chemical properties of non-conventional materials that are widely used in terrorist activities in the hopes of developing techniques to mitigate explosives-related threats.

In order to understand how these chemicals are altered to become explosive, Mihindra performed experiments to determine the effects of physical and thermal conditions (e.g. pressure and temperature) on chemical properties on three types of oxidizers: nitrate, perchlorate and peroxide.

When asked about her experience working on this project, Mihindra describes her enthusiasm for the breadth of information that she was able to acquire just by tuning the physical variables (e.g. pressure) of these chemicals.  Regarding the project’s overall mission, she states, “I’m passionate about how this can be used in real life applications, and that it can change people’s lives for the better.”

Mihindra has been drawn to physical chemistry since high school, and received her B.S. in Chemistry from the University of Colombo in Sri Lanka. She was originally introduced to Prof. Yoo’s research while at WSU on a prospective visit before accepting their offer to join the Ph.D. program in 2008. Of her experience working with Prof. Yoo, she remembers being encouraged to investigate the scientific basis of experimental observations on her own, instead of being handed the answers, and says, “It made me a better scientist.”

In her new role as a postdoc at the University of Utah, Mihindra has the opportunity to demonstrate her skills and experience from her previous project, while also getting the chance to explore new scientific techniques. Her current project, “Superconductivity of Lithium Rich Compounds,” will give her the chance to study the effects of high pressures and low temperatures on chemical properties, and will offer her the opportunity to get more experience with x-ray diffraction techniques. When asked about her career goals, she undoubtedly wants to continue doing research on explosives where she would like to have a positive impact on society, and would one day like to work for a national lab.

Mihindra’s enthusiasm for her work becomes quickly apparent when speaking with her, and is further reinforced by Prof. Yoo, who reflects, “She was smart, careful, responsible, and highly motivated both in her research and academic leadership roles… in short, she was an excellent graduate student with a high level of devotion and morale.”

Naval Academy Midshipmen Participate in ALERT Research July 1, 2015

Annapolis Naval Academy Midshipmen, Andrew Kelly and Gabe Lackey, are spending a month this summer doing ALERT research at the University of Rhode Island (URI), in Kingston, RI. Andrew and Gabe are Systems Engineering majors and have elected to use this time to work with the URI Energetic Materials Research Group. Their work includes hands-on experience with a myriad of aspects of explosives research at both the laboratory scale and in the field. Projects include using various instruments for physical characterization of both military explosives and homemade/improvised energetic materials.

Midshipman Lackey (pictured, middle) has said of his experiences,

“It has been very interesting to see the ‘behind the scenes’ process that takes an idea and eventually lets it reach the front lines, helping sailors, marines, and all military men and women.”

Midshipman Kelly (pictured, far right) says of his experiences working with ALERT scientists at URI,

“Working alongside the graduate students under Dr. Oxley has been informative in linking the numerous research areas to future military application, as well as what is currently being used.”
