Engineers Week 2017: The Good News is Female Engineers are in Charge!


I am pleased to tell my readers that we’ve just celebrated one of the most memorable Engineers Weeks in recent memory. We’ve been invited to several award banquets and proclamation lunches with colleagues from ASCENCS, including the president and my good friend Jordan Pitt. We were delighted to see that all keynote speakers and many awardees were women engineers. That is why this month, I’ve decided to write about women engineers. Especially two extraordinary women engineers, Dr. Ericsson and Dr. Pehlivan. You may already know them since they are celebrities. But first, a brief background and some statistics:

Who was the first woman to receive a degree in engineering? Elizabeth Cady Stanton received her civil engineering degree from Cornell University in 1905. Over the past few decades a growing number of women have been entering the field of engineering, but many believe this good news doesn’t have a rosy ending. As recent coverage in the media, including National Public Radio, details, many female engineers are leaving their positions and some are hesitant to enter the profession at all. For the civil engineering community, the statistics demonstrate that we are doing better than most, yet we have much more work to do.

Statistics show that women represent 12.1% of the civil engineering workforce and 14% of the total workforce. And according to the Engineering Workforce Commission (EWC), over the past five years, civil engineering has consistently outpaced all other engineering disciplines in the awarding of Master’s and Doctoral degrees to women.

Aprille Joy Ericsson, PhD:

Dr. Aprille Joy Ericsson is the New Business Lead for the NASA GSFC Instrument Systems and Technology Division at NASA Goddard Space Flight Center.

Most recently, she served as the Capture (Mission) Manager for a proposed Astrophysics Mid-sized Class Explorer of $250M, called STAR-X. Prior to that proposal development, she served as the NASA GSFC Program Manager for Small Business Innovative Research/ Small Business Technology Transfer Research. Formerly, she has served as the Deputy to the Chief Technologist for the Applied Engineering and Technology Directorate at the NASA Goddard Space Flight Center (GSFC) with a primary focus as a Technologist for Advanced Manufacturing, Applied Nanotechnology, miniaturization of Technology for CubeSat and SmaliSat space platforms.

During her 25+ year tenure with NASA, she has held numerous positions. She was an Attitude Control Systems analyst developing practical control methods and analyzing structural dynamics for X-Ray Timing Explorer, Tropical Rain Forest Measurement Mission, Transition Region & Coronal Explorer, and Wilkerson Microwave Anisotropy Probe. As a NASA HQs Program Executive for Earth Science, and a Business Executive for Space Science, she supported the SORCE and ICESat missions. She was an Instrument Project Manager leading spaceflight instrument teams and proposal development. Also, her aerospace research at Howard University was developing control methods for orbiting large space platforms like ISS.

Dr. Ericsson has also served as an Adjunct Faculty member at several Washington DC Area Universities. She sits on several Technical Academic boards at the National Academies, MIT and previously Howard University where she also served as a member of the Board of Trustees.

Of her numerous awards and recognitions received over the years, the most prestigious was “The 2016 Washington Award” from the Western Society of Engineers. She is the first female (and the first African-American female) to receive a PhD in Mechanical Engineering from Howard University, and the first African – American female to receive a PhD in Engineering at NASA GSFC. She received her BS in Aeronautical/Astronautical Engineering from MIT. She grew up in Brooklyn, NY and has one daughter, Arielle Ericsson-White.

Menzer Pehlivan, PhD, PE:

Dr. Menzer Pehlivan is a well-known   PE, featured in ASCE’s “Dream Big” IMAX movie. Dream Big: Engineering Our World debuts in museums and theaters around North America during the Engineers Week.

Dr. Menzer Pehlivan is a geotechnical engineer specializing in earthquake engineering. She is currently working at CH2M in Seattle, WA. She is an expert in the analysis of seismic site response, liquefaction and other natural hazards, soil-foundation-structure interaction, probabilistic seismic hazard analysis (PSHA), and the seismic design of foundation of structures. She was inspired to build more resilient communities and reduce the risk associated with the earthquakes following the 1999 Kocaeli Earthquake that hit Turkey.

Upon completing her undergraduate degree in Civil Engineering, she pursued graduate studies specializing in geotechnical earthquake engineering. She obtained her doctorate from The University of Texas at Austin in 2013 and started working as a consulting engineer in New York City, where she had opportunity to work on seismic design of projects in the US, Mexico, and Canada. During this time she also served as an Adjunct Professor at Manhattan College where she developed and taught the seismic portion of a graduate course for practicing engineers on fundamentals of foundation design.

She has been actively involved with pioneering research projects advancing the state-of-art and state-of-practice of geotechnical earthquake engineering. She led a part of NGA-EAST research effort regarding the modelling of the uncertainty in regional soil effects of Eastern-North America. Following the 2015 Nepal Earthquake, she was one of the appointed members of the Geotechnical Extreme Events Reconnaissance (GEER) team to travel to Nepal and perform post-earthquake reconnaissance. Dr. Pehlivan published several journal and conference papers and serves as reviewer for Earthquake Spectra.

Next month we will talk about “Ten Reasons to Love Engineering.”

Reflecting on 2016: Remembrance of Dmitri T Clemons


It has been almost three years since Ranjit Sahai, Chris Manalo and LJ Sauter of ASCE-NCS decided to have a new column in the monthly eNewsletter for students and practicing engineers. That was the beginning of “Dr. Z’s Corner” and the rest was history. As I reflect on 2016, we had some good and some sad news to report. On a personal note, I was pleased to receive another national award, this time from ASEE and the news of ASCE-Fellow. For the sad news, I will share with my readers a letter that I received from Cherod Gregory Hicks, President of ASCE Student Chapter at Morgan State University.

Remembrance of Dmitri

“My name is Cherod Hicks and over the past semester, I had the honor and privilege of serving as the President of the American Society of Civil Engineers (ASCE) at Morgan State University, located in Baltimore, MD. When I was nominated for the position, my first question was, “Who will be serving as my Vice President?” I understood then, as I understand now, without a strong support staff and executive committee, I would be unable to maintain a high standard of excellence that ASCE student chapters hold near and dear to the oldest engineering society in our nation’s history, founded in 1852. When I found out it would be Dmitri Clemons, I was excited and couldn’t wait for the fall 2016 semester to begin because I knew his work ethic was unparalleled amongst any student in the Department of Civil Engineering. We would bounce ideas off of one another and whenever I questioned my purpose in the field of civil engineering or wondered aloud if I could be successful, he always reassured me by letting me know that the only person that could stop me from achieving my goals was myself.

“Dmitri T Clemons was born in Silver Spring, MD on November 5, 1994 to Lynn Clemons. He was educated in the Montgomery County Public School system, where he graduated from Paint Branch High School in 2013. He was a member of the Varsity football team and he threw Shot Put for the track team. Dmitri was an avid reader and he loved working out. On any given day, you could find him running through campus or working out in the gym. Upon graduation, he attended Morgan State University, where he majored in Civil Engineering. In 2013 and 2014, he received a Certificate of Academic Excellence for making the Dean’s List with a 4.0 GPA. He was named Vice President of ASCE, Morgan State Chapter his Junior year and he continued in that role his senior year. He traveled to Philadelphia, PA for the Global Competitiveness Conference and he also traveled to Pittsburgh, PA and Boston, MA for the ASCE Conferences. In June of 2016, he was selected by the Congressional Black Caucus Foundation Emerging Leaders to represent Morgan State for the US-China Study Delegation. Along with being a member of ASCE, Dmitri was also an active member of the National Society of Black Engineers and the American Society of Highway Engineers.

“It is with sadness and a broken heart that Dmitri passed away on September 21, 2016 after working out. He had a near perfect GPA and his mother received his Bachelors of Science in Civil Engineering posthumously on his behalf at the December 2016 Commencement. He is as missed today as he was the moment we found out he taken his last breath. It is incredibly sad that his life ended so prematurely when we all recognized that greatness had already tapped him as the next great leader in the field of Civil Engineering. He had aspirations of pursuing his PhD after graduation and was inspirational to his fellow classmates to pursue greater goals as well. He started a GRE study group and he was instrumental in informing us that he was attending Dr. Z’s pro-bono Saturday classes at UDC (University of the District of Columbia). I, Cherod Hicks, and Phine Ulysse attended our first class with Dr. Z today and it was one of our best academic experiences to date. It would not have been made possible without Dmitri taking those first steps when he attended those sessions during the summer of 2016 and showed us how much he was learning and technical application he was taking away from Dr. Z. If he were here, he would tell us to smile, suck it up, stop making excuses, and study. Even though he is gone, he will never be forgotten because we all carry a part of him along with us every step we take, especially as we matriculate through our careers and personal lives. Dmitri T Clemons, we miss you, we honor you through our actions, but most importantly, we love you! Rest in Peace Big Homie, God’s got you now.”

Cherod Gregory Hicks,
Morgan ’16, Civil Engineering

I would like to close with uplifting news. Starting next month, we will welcome two new contributors that will be helping us: Dr Lei Wang in Geotechnical and Dr Bryan Higgs in Transportation concentrations.

Until next time,
