    WORKING TOWARD A CURE: PhD student Christopher Pacia 
    smiles for the camera
    Why haven't we found a cure for cancer yet? This is the question that motivates Christopher Pacia when he's doing research in the Chen Ultrasound Lab at Washington University in St. Louis (WUSTL). Pacia is a PhD student in biomedical engineering, and his research focuses on ultrasound imaging and therapy that can impact cancer patient care. "With a greater understanding of the brain, treatments can be more patient-specific," says Pacia. "In that way, they will also be more effective in improving the lives of those affected by the seemingly boundless complexity of neurological disorders."

    Pacia is the current Vice President of the SPIE Student Chapter at his university, under the supervision of 2019 SPIE Britton Chance Award winner, Dr. Samuel Achilefu. The chapter is involved in a variety of local outreach activities which, according to Pacia, is one of the most rewarding parts of being a researcher.

    1. Share the story of your favorite outreach experience.

    One of my favorite outreach experiences was my trip to the local St. Louis Science Center during its annual SciFest event. SciFest is free and open to the public, and it's where scientists, engineers, and doctors come together to show all the amazing things happening around St. Louis. Hundreds of attendees have the chance to walk around and learn about motion-capture technology in movies, how memories are formed in the brain, and how optics acts as a window into our bodies.

    Our SPIE Student Chapter went to SciFest to put on an exhibit, showing children and adults the science behind ultrasound imaging. Our booth had hands-on demonstrations to showcase the fundamentals of sound, and the ways in which ultrasound can be used for imaging. We even let the brave, young scientists try to image their own arm! The kids loved playing with sound and trying to see what they look like on the inside. Even adults were amazed when we explained how fetal ultrasound images were formed. The amount of shock and awe that comes from building an understanding in science has been one of the most rewarding parts of being a researcher.

    2. Explain your current research and what you do at your job. How does your work impact society? 

    A question people are always asking is: Why haven't we found a cure for cancer yet? But, of course cancer research isn't as straightforward and simple as we would hope, especially in the case of brain cancer. The main challenge when treating brain cancer is the presence of the blood-brain barrier (BBB). The BBB has the important task of regulating the diffusion of molecules between the brain and blood vessels. While this is beneficial in protecting neural tissue from foreign pathogens, the BBB also prevents life-saving drugs from being delivered to the brain.

    In the Chen Ultrasound Lab at WUSTL, we are working with focused ultrasound (FUS) to non-invasively disrupt the BBB and enhance drug delivery to the target area. The integration of FUS with magnetic resonance imaging (MRI) allows for more precise targeting, so by developing an integrated FUS system, clinicians will be able to use their MRI scanners to non-invasively enhance cancer-drug delivery. This will take us one step closer to developing a cure for cancer.

    3. When you look five years into the future, what do you hope to have accomplished? 

    In five years, I hope to have completed my PhD research and be involved with further developing diagnostic and therapeutic tools for the clinic. The necessity for this technology is clear, and with my training I plan on making great strides to improve patient care. My goal is to have developed a system that can help answer at least one question about the brain. Whether it has to do with remapping after disease, the effects from aging, or the enhancement of cognitive processes from neuromodulation, I will want to have my hand in a revolutionary tool that will shape the future of science.

    On a more personal level, I'd like to influence the future generations of scientists. The next generation of researchers will have a greater amount of resources, technology, and mentors at their disposal to address any unanswered questions. I will continue to reach out in my community to share what I have learned, and, hopefully, inspire students to pursue a STEM career and push the envelope of science. If I persuade just one student, the five years will have been worth it.

    4. What is your advice to others in the STEM community?

    Building a diverse community and sharing knowledge with each other will push STEM further into the future. There have been great strides in the scientific community in terms of reaching out and encouraging underrepresented minorities to pursue STEM careers. There has been a lot of progress, but it cannot stop there.

    There are a number of ways to help. To name a few: going out into local schools and showing students that science is fun is the catalyst to helping students recognize their potential; providing students with the resources to run hands-on experiments will prepare them for a future career in STEM; putting on demonstrations at the science center will help students appreciate how science is used in our everyday lives.

    WHEN IN ROME...: When he's not working toward a cure for cancer, Pacia loves to travel!

    CEO POWER: Dr. Misty Blowers
    From the US Air Force Research Lab to Vice President of Cybersecurity at ICF to CEO of her own defense consulting company, SPIE Member Dr. Misty Blowers continues to make waves in the defense security world. She has always been unwavering in her dedication to this community, citing her drive toward positive change: "I hope to make a technical contribution that can make the world a better place."

    Many would say she's already accomplished this. In 2018, Dr. Blowers was awarded the SPIE Early Career Achievement Award for her dedication to advancing applied machine-learning solutions to help solve real-world problems. Her commitment to the field also shines through in her multiple years serving on SPIE conference committees at SPIE Defense + Commercial Sensing (DCS), and her 2016 publication of Evolution of Cyber Operations and Technologies to 2035 (Springer) which she discusses in the interview below.

    Enjoy the interview!

    Achievement Award
    1. Describe a memorable moment from an SPIE conference.

    SPIE supported an idea I had for a conference to bring in student speakers to talk about what they believed the next disruptive technology will be that will change the world. The students did a fantastic job and provoked discussions across a global community of experts. This is happening again this year at SPIE DCS in Baltimore!


    2. Explain your current research/what you do at your job. How does your work impact society?

    I started my own business in 2018, called Datalytica LLC. My motivation was to provide more breadth of technical consulting services to help advance the state-of-the-art emerging technologies across the US Department of Defense (DoD).

    Along with numerous speaking engagements, I currently serve as a technical advisor to the Chief Scientist at the AF Rapid Capability Office. This is a dream job as it allows me the opportunity to align short-term warfighter needs with technologies coming out of the laboratories across the industry.

    My prior role as the Conference Chair of the Machine Intelligence and Bio-inspired Computation: Theory and Applications Conference and my current role as the Chair of the Disruptive Technologies in Information Sciences Conference at SPIE Defense + Commercial Sensing plays a big role in helping me build my professional network and stay current on the latest emerging trends across the information sciences domains.

    SUN TIMES: It's important to step out of the
    lab!
    Last but not least, I teach a class at George Mason University on Blockchain Technologies. This is an evolving field with a global community of developers. The incentive to create a new architecture that advances across many different computer science topics is unlike anything I have ever seen. These new applications are driving global trade, communications, and domestic policy and regulations. Not only have advancements been made on computer hardware architectures, but we also see profound advancements on how to implement peer-to-peer networking, layered cryptography, smart contracts, and even artificial intelligence. It's incredible.


    3. You teach a course on blockchain at George Mason University, and will be teaching one at SPIE DCS next month. What excites you about this course and what motivates you to continue teaching it?

    I love to teach this course because it allows me to stay current in my field while simultaneously dispelling any misconceptions people have about where this technology is headed. I find these architectures are often misunderstood because there are so many different blockchain architectures that exist today. There are also many new applications of blockchain technologies--specifically in the crypto-currency domain--that the world needs to take notice of because this technology is being used by nefarious actors just as frequently as it is being used for good.

    Blockchain technologies have the potential to solve global privacy and security concerns, but also the ability to enable underground crime syndicates in a way never before thought possible.


    4. Share the story of your favorite outreach or volunteer experience.

    My favorite outreach experiences have been my speaking engagements with students at both the high school and college level. I love to interact with bright young minds that have so many fresh new insights in this rapidly changing world.

    WINNER, WINNER: Blowers receives the 2018 SPIE Early Career Achievement Award at 
    SPIE DCS from Arthur Morrish and Jim McNally.

    5. Have you ever had to embrace failure? Describe a challenging situation, either personal or professional, and how you overcame it.

    The first 14 years of my career as a computer scientist were challenging, and I did not always feel like I was advancing as quickly as I hoped. I felt these challenges were attributed to the fact that I was a female computer scientist in a male-dominated workplace. At the time, the US Air Force Research Laboratory (AFRL), where I worked, showed a clear pay gap between the female PhDs and the male PhDs. This prompted me to work a lot harder than my male counterparts, and I often took on additional roles and responsibilities to try to get ahead.

    One of these roles paid off. I was participating in a NATO workshop focused on the "Measures of Effectiveness of Cyber Operations" when my contributions were noticed by a senior-level defense contractor who was also in attendance. As a result, his company recruited me from my position at the US AFRL to take a position as the Vice President of Cybersecurity Research at ICF. This was a big career leap. I had oversight over the technical direction of a division of over 320 scientist and engineers. In the first year alone, I secured over $175 million in new work for the division.

    6. What book has impacted your professional life the most? Your personal life? Why?


    My book, Evolution of Cyber Operations and Technologies to 2035. An entire community of leading researchers came together to contribute to this book with a passion to educate the world about where they felt cyber operations and technologies are heading.

    As a cyber subject matter expert at various US DoD wargames, I noticed that they were often focusing their strategic planning about a 2035 fight with 2015 technology.  In response I initiated a federal government, academia, and industry-wide effort to educate a global community on future technology gaps in information sciences by writing and editing this book.

    SATELLITE SELFIE: Blowers spends time at the 
    National Air and Space Museum in Washington, DC.
    I assembled and coordinated the technical content, leading a team of 17 contributing authors from federal agencies such as The Joint Chiefs of Staff, The National Air and Space Intelligence Center (NASIC), The National Security Agency (NSA), Naval Postgraduate School, and The Air Force Space Command (AFSPC). This foundational scientific publication serves as a resource for wargame planning and provides a strategic vision for the future direction of cyber operations. By creating and publishing this material, I strengthened collaboration across government agencies to promote a culture of cooperation to drive future investment into key technologies, giving the US DoD a strategic advantage. 

    You will see that my book was published in 2016, which means it was written in 2015. Since this time, a lot has changed. I would welcome any interest in contributing to the next book!


    7. What is your advice to others in the STEM community?

    Value your family, peers, friends, and other researchers from across the global community. Even when we disagree, we can find common ground and learn from each other.

    OH, SNAP!: Blowers poses with a crocodile at SPIE DCS 2017.
