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.”

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.”
ALERT Summer Research Experience for Undergraduates (REU) Begins July 1, 2015
This summer, ALERT is hosting 5 undergraduate students who are participating in the 10-week REU program. At Northeastern University, two students are working with Prof. Carey Rappaport, one student is working with Prof. Jose Martinez, and one student is working with John Beaty. ALERT is also hosting a student at the University of Puerto Rico Mayagüez who is doing research with Prof. Samuel Hernandez.
The ALERT REU program is partnering with other REU programs in the College of Engineering to build a cohort of students who jointly attend professional development meetings and program activities. At the end of the summer each student will give a final presentation on their research project.

Watch the Latest ALERT 101 January 30, 2015
ALERT is proud to present the third installment of ALERT 101. This chapter’s topic focuses on Methods of Chemical Characterization and Mitigation, and is part 1 of a 2 part series. ALERT Thrust Leaders Jimmie Oxley (Thrust 1) and Steve Beaudoin (Thrust 2) provide commentary about the crucial role of chemical characterization in the mitigation of explosives-related threats, and how ALERT research is helping first responders and security personnel to detect and eliminate threats before they can be used for malicious reasons.
Chemical characterization for the purpose of explosives detection requires ALERT researchers to classify what are explosive materials, and what are not. In the lab, researchers observe how chemicals uniquely react to stimuli, thus determining their chemical properties. For example, Differential Scanning Calorimetry subjects the chemical samples to heat, thus producing a specific reaction that can then be compared to the Explosives Database managed by the University of Rhode Island to determine if the chemical is a volatile substance.
Researchers then leverage these chemical characterizations to develop sensors that detect explosive threats. Trace analysis techniques are used to sense when chemical residues are present on surfaces of or in the air around materials by picking up small quantities of the chemicals when they are in the solid or vapor phases. One such trace method uses a polymer swab developed by Prof. Beaudoin, to sense chemicals in the solid phase on an object’s surface. This swab has individual fingers, similar in design to a toothbrush, with chemical head groups attached to the ends that attract and hold the residue to the finger. ALERT continues to advance the state-of-the-art in both solid and vapor trace technologies through their recently established Trace Explosives Sampling for Security Applications (TESSA) workshops.
As a supplement to this installment, stay tuned for ALERT 101: Basic Properties of Atoms and Molecules, coming this spring!
Inspired by the success of TED (www.ted.com) and other educational media forums, ALERT has developed the ALERT 101 video series. Each video short features different technologies and research areas that the ALERT Center engages in. We hope that these productions help educate and inform the global community on these topics in an accessible and enjoyable way.
Michael B. Silevitch and Simon Pitts awarded 2015 Gordon Prize January 9, 2015
ALERT Center Director, Michael B. Silevitch and Gordon Engineering Leadership Director, Simon Pitts have been awarded the 2015 Bernard M. Gordon Prize for Engineering Education by the National Academy of Engineering (NAE). Prof. Silevitch, who is the founding director of the Gordon Engineering Leadership Program (GEL) at Northeastern University, is recognized alongside Simon Pitts “for developing an innovative method to provide graduate engineers with the necessary personal skills to become effective engineering leaders.”
The GEL Program is a graduate curriculum offered through NEU’s College of Engineering, with the mission of creating an elite cadre of engineering leaders “who stand out from their peers in their ability to invent, innovate, and implement engineering projects from concept to market success.” Each year, a select number of Candidates pursue the program, which is based in “three-way mentorship.” Students are assigned to one mentor from the program, one from an industry partner, and another mentor who has expertise in each student’s field of interest.
Prof. Silevitch created, acted as its initial director, and is now a lead mentor for the students participating in the GEL program. When asked what receiving the Gordon Prize means for GEL, he explains:
“It’s a validation of the importance of developing a program for engineering leadership that will help our country maintain its international competiveness, in terms of technological innovation.”
The Bernard M. Gordon Prize for Innovation in Engineering and Technology Education was initiated in 2001 by NAE with the intent of recognizing new modalities and experiments in education that develop the next generation of effective engineering leaders. The Gordon Prize focuses on education innovations including “curricular design, teaching methods, and technology enabling learning that strengthens students’ capabilities and desire to grow into leadership roles.” This prestigious prize is one of 5 NAE annual awards established to “recognize leaders in engineering for their lifetime dedication to their field and their commitment to advancing the human condition and to bring better understanding of the importance of engineering and engineering education to society”.Read More
