We begin the final week of Women’s History Month by saying hello to our very own Mason Korea professor Dr. Sohyun Park.

Dr. Sohyun Park is an assistant professor of Computational and Data Sciences at George Mason University, Korea. She earned her doctorate in geography from The Ohio State University. Her research focused on the socio-environmental change in the Korean strawberry industry. Her research lies at the intersection of environmental science, economic geography, and spatial data analytics. She is interested in socio-environmental inequality in the context of the growing interdependency between places (e.g., linked via food trade and residential migration).

When we asked her, “What words of wisdom do you have for other women who are just beginning their journey’s in STEM?” Her response was,” Welcome aboard! I believe that it is essential to be open to learning and trying new things and never be afraid to ask for help or guidance. I would encourage women to find mentors and role models who can provide support, advice, and encouragement.”

Everyone say hello to Dr. Annie Hui

For over ten years, Dr. Hui has had the opportunity to meet and talk with many women at the start of their STEM journey. Dr. Hui mentioned women starting in STEM come from all kinds of backgrounds and have very diverse expectations on what STEM has for them. Some do STEM because of personal interest. Some want to acquire useful skills that lead to better job prospects. The challenges and obstacles faced by women in STEM are many and diverse. Examples include, but are not limited to, inferiority feelings, stereotypes, debts, exhaustion, family, social unrest.

To Dr. Hui It seemed that the greatest encouragement that keep a woman going is the conviction that she is on a good path. Sometimes, this could mean putting all her energy into her work to make quick progress in her career. Other times, it could mean stepping back from the next big career opportunity to give priority to people she loves. Yet other times, it could mean persevering on doing good against the tide.

When we asked her, “What words of wisdom do you have for other women who are just beginning their journey’s in STEM?” Her response was, “Stand at the crossroads and look; ask for the ancient paths, ask where the good way is, and walk in it, and you will find rest for your souls.’ (Jeremiah 6:16)”

We continue our Women’s History Month Celebration this week with our next amazing faculty member, say hello to Dr. Holly Russo!

She has worked with the federal government in national security and defense since 2002 and she is a US Air Force veteran. After having been a researcher at the RAND Corp. and Center for Naval Analyses, and working at other large and small companies, she decided to start her own woman-owned, veteran-owned small consulting firm Cybélé Data Advisory LLC. They are now teamed with a larger firm providing support to DARPA, and with other large firms on other potential opportunities.

She is currently assisting a DARPA Program Manager in leading a $65M research project developing approaches to make it easier for scientists to build, maintain and reason over rich models of complex systems including physical, biological, social, engineered or hybrid systems.

Her broader passion is in facilitating team success in government research and data operations. She seeks to bridge the communication gap between the C-suite / Flag Officer leadership and data teams, to build sustainable and effective data operations that deliver real value.

We asked her, “What words of wisdom do you have for other women who are just beginning their journeys in STEM?” Her response:

Trust your vision: I think there are two key mistakes I’ve made throughout my career, which I want to help others avoid. These are things to which women are particularly susceptible:
1. Don’t stop working on something because someone else tells you that what you’re doing isn’t important; it could be that they lack the vision you have. Make your own decision about whether something is important.
2. Don’t assume that something you’ve developed is too simple or not novel or couldn’t be right. I failed to publish one paper that would’ve turned out to be pretty significant years later, simply because I didn’t trust that I could actually be right. Years later, things evolved just as I said they would in my paper, but I never published so I missed a major opportunity. I’ve failed to follow up on other things because I thought that they were too simple, or not new. I always wound up kicking myself years later.

This dissertation introduces a new search theory methodology, nicknamed Pathfinder, that can optimize teams of heterogeneous mobile and stationary searchers as well as searchers that can transport other searchers. In addition, Pathfinder can optimize searches over a multi-zone domain and model target behavior based on environmental and behavioral factors. Pathfinder accomplishes this by using an agent-based model to estimate target movement; then it uses nonlinear optimization, teamed with a genetic algorithm, to find optimal search plans. The optimization model considers that search plans should be easy to both implement and create in reality, in addition to having a high probability of finding a target. Thus, the optimization model includes movement constraints that make search plans easier to implement and more cost effective. The obtained results from numerous simulations demonstrate that the methodology has the potential to advance current search theory as well as to enhance current maritime search operations.
