Preparing to Explore New Worlds: ChBE Alum Robyn Gatens Acting Director of International Space Station

Robyn Gatens

It’s a busy time at NASA. The next chapter of human space exploration is underway. It’s been more than 50 years since Neil Armstrong took those first steps on the moon and 48 years since Gene Cernan – the last man on the moon –  climbed back into the lunar module to return to Earth.

Now, NASA has decided to return to the moon with its Artemis program by 2024, but this time they plan to stay. It’s all part of an effort to explore deeper into space – more specifically, land humans on Mars. But to go further than the moon, NASA must learn how to sustain missions of much greater distance and duration. Astronauts must also overcome radiation, isolation, gravity and extreme environments to stay healthy. NASA believes developing a sustainable human presence on the moon is the best next step in helping astronauts prepare for making the voyage to Mars.

Alumni Profile: Rene Guermonprez of Aptar CSP Loves Developing Engineering Talent​

Rene Guermonprez, ChBE 1989, say she’s grateful for the many people who looked out for her on her way to becoming the first college graduate in her family. And now she’s committed to paying it forward.

Those who facilitated her journey included not only many professional mentors, but also a family she babysat for who allowed her to use their car to reach her classes at Armstrong State University, where she first earned a degree in chemistry before coming to Georgia Tech’s School of Chemical & Biomolecular Engineering.

As she worked summers as an intern at the Union Camp paper mill in Savannah, Georgia, engineers there recognized her potential and encouraged her to come to Tech. “I worked in the chemical development area at the mill and realized I needed a chemical engineering degree to advance,” she says.

Guermonprez, who grew up in Long Island, New York, and moved to Savannah in 10th grade, says she never took the help and guidance she received along the way for granted. “Now it’s inherent in me to try to do the same for others,” she says.

Alumni Profile: Savannah Lee's Goals for Fulbright Studies Involve Helping Disabled

Georgia Tech alumna Savannah Lee, ChBE 2018, wanted to win a Fulbright scholarship so much that she sprinted 2,000 feet up a remote mountain in Montana in order to find a cell signal. She’d needed to reach those writing her recommendations.

A Stamps President’s Scholar at Tech, Lee was leading a two-week, team-building expedition of incoming scholarship recipients through the Montana wilderness last August that coincided with the application process.

By late March, she learned that she’d won a Fulbright scholarship to cover her tuition and living expenses as she earns her MBA in international human resources at National Taiwan Normal University in Taipei from fall 2019-spring 2020. “I screamed when I saw the e-mail,” she says.

Sponsored by the U.S. Department of State and the J. William Fulbright Foreign Scholarship Board, the Fulbright Program is the flagship international educational exchange program, designed to increase mutual understanding between residents of the United States and people of other countries.

Alumni Profile: Ashley Hancock Develops Medical Device to Curb Opioid Abuse

As the opioid addiction crisis grew to epidemic proportions, Georgia Tech alumnus and entrepreneur Ashley Hancock saw an opportunity to save lives while working with a physician and an addiction specialist. They have developed a medical device that can help patients adhere to prescribed dosages by controlling access to their medication and dispensing it properly.

In 2013, the team founded the Atlanta-based company Intent Solutions, whose iPhone-sized smart-dispenser alerts users when it’s time to take their painkillers and only dispenses the amount prescribed via thumbprint sensor, never giving anyone access to the entire contents of the medication. The device collects and transmits adherence data via the cloud to monitoring organizations and caregivers. It can detect too frequent attempts to access pills or if anyone other than the patient is trying to reach the medication stored in the tamper-resistant device.

“Even though the opioid crisis may not have been as broadly known then as it is today, once we dug in and did the research, the problem was evident, with people dying every day and tremendous associated costs,” says Hancock, a strategic marketing professional who earned his BS from the School of Chemical & Biomolecular Engineering in 1990.

Alumni Profile: Lucy Pettitt-Schieber Ensures Integrity of BP’s Gulf of Mexico Wellstock

Lucy Pettitt-Scieber

For the first few years of her career, Lucy Pettitt-Schieber was one of only several women – and the sole female engineer – working and living on one of the oil rigs operated by BP in the Gulf of Mexico.

After earning her BS from Georgia Tech’s School of Chemical & Biomolecular Engineering (ChBE) in December 2012, she started as a well intervention engineer with BP the following year, executing operations on the rig to help fix issues with any of the wells in the Gulf of Mexico.

“I had a great experience. Everyone looked out for me as a junior engineer. They knew I was there to learn. While I didn’t have a whole lot in common with the other rig crew, I grew up playing sports, so I could relate to people on that level.”

She adds: “Living on the rig two weeks on, two weeks off was important to understand all of the equipment involved as well as the lifestyle and the vocabulary. Everybody has a different word for every piece of kit on the rig. By the time you get back in the office, you’re ready to write the procedures you learned to execute out there.”

Alumni Spotlight: Jim Tucker Survived Bomb Disposal Duties in World War II, Building Successful Career in Pulp and Paper

Alumnus Jim Tucker

After he interrupted his studies at Georgia Tech to serve in World War II, Jim Tucker (ChE 1947-Co-op) opted to train in the U.S. Army’s bomb disposal program, learning the design of German, Japanese, Allied, and U.S. bomb fuses, and how to identify them by touch.

“My choice of bomb disposal was based on several factors, the primary one being a desire to save lives, not take them. I also had confidence in my abilities which included attention to detail. I had repaired clocks and other mechanical devices since I was 10, taking them apart and reassembling them. I could also remain calm during crises, and had the ability to organize and direct a group.”

Today, at age 95, Tucker is one of two surviving members of the “Co-op Boys,” a group of his classmates in metro Atlanta who were called for duty after enrolling at Tech in 1939 and 1940. Tucker and fellow alumnus/veteran James Ivey still meet for lunch every other month with Marilyn Somers, director of Georgia Tech’s Living History Program.

“Our group discussions have allowed me to recall memories long stored and forgotten,” he says.

Tucker knew he’d be called for duty as soon as the Japanese bombed Pearl Harbor at the end of the first quarter of his sophomore year. Though he hoped he could wait until after graduating with his chemical engineering degree, he was called to active duty in April 1943.

When he selected the bomb disposal specialty, he learned it had a saying – “You go up fast!” – with a double meaning: Your military career could blow up with promotions, or you could from mistakes.

The bomb-disposal techniques he learned had been developed by the British Royal Engineers, who lost 360 of the 400 men initially assigned to this trial and error project.

Alumni Spotlight: John Burson


At the May 2017 doctoral and master’s Commencement ceremony, Georgia Tech awarded an honorary doctor of philosophy degree to John H. Burson III, ChE 1956, MS MET 1963, Ph.D. ChE 1964. This is the highest honor that can be bestowed by the Institute.

The embodiment of a 21stcentury Renaissance man, Burson is a physician, a former Georgia Tech professor, a military veteran, an involved community citizen of his hometown (Carrollton, Georgia), an enthusiastic volunteer, and a generous philanthropist.

Tours of Duty
A retired Lieutenant Colonel in the U.S. Army, Burson served in the Army Reserves for 30 years. At the age of 70, Burson asked that he be returned to active duty, and he was deployed in Iraq for three tours in 2005, 2006, and 2007, and in Afghanistan in 2009 and 2011 as part of the military’s “Boots on the Ground Physician’s Program.” He earned combat medical badges and commendation medals.

Burson, who earned his medical degree from Emory, has had a distinguished medical career that includes service as chief of staff and chairman of the board of trustees for Tanner Medical Center from 1994-2012, an active member of the Tanner Urgent Care Clinic staff, and a self-employed physician at the Villa Rica Ear, Nose, and Throat Clinic.

He is a licensed diplomat of the National Board of Medical Examiners, a fellow of the American Board of Otolaryngology–Head & Neck Surgery, and a fellow of the American College of Surgeons. He is also a professional engineer licensed in Georgia, Pennsylvania, and California. In the academic arena, Burson was an associate professor and adjunct professor in chemical engineering at Georgia Tech from 1959-1975, an assistant professor at Emory University School of Medicine, and a principal research engineer at the Georgia Tech Research Institute’s predecessor institution from 1959-1975. He received the Regents Award from the University System of Georgia Board of Regents in 2015.

He has made extensive philanthropic contributions to Tech through the years.

Alumni Spotlight: BP's Keisha Wilson Tanner

Alumnus Keisha Wilson Tanner

Keisha Wilson Tanner has rarely feared moving outside of her comfort zone – from volunteering for unfamiliar career opportunities to living for a year on an oil-and-gas production/drilling platform.

Tanner – area team lead for BP’s Thunder Horse facility in the Gulf of Mexico – says, “Your career is not going to be as successful as you’d like if you’re comfortable all the time. You have to embrace change and accept new challenges.”

Inducted into the College of Engineering’s Academy of Distinguished Alumni in spring 2016, Tanner says she took on a major personal challenge even enrolling at Georgia Tech

A native of Nicholls, Georgia, she barely knew anything about the Institute before making a last-minute switch from attending Mercer University to accepting a Georgia Tech scholarship after a persistent bid to recruit her.

“I thought that if they were going to put this much effort into recruiting me, I was going to give it a shot,” Tanner remembers.

Competitive Streak

However, the academic challenge was initially a shock for her. Soon after she started, a family friend told her mother that she should bring Tanner home because she was surely “in over her head” having come to Tech from a small-town high school.

Tanner then posted the saying “Keisha is in over her head” on her dorm room wall, not as an admission of defeat, but as a challenge that she would emerge from successfully. “It was exactly what I needed to hear. I’m a little competitive, so it was on!,” remembers Tanner, who found time to be a cheerleader for the Atlanta Falcons, dance for the Georgia Tech band, and serve as Miss Atlanta 1994.

“My time at Tech taught me that there’s not anything I can’t do. You can drop me in the wilderness, and I’m going to get out. Drop me into an ambiguous situation with no obvious solution, and I’m going to figure it out.”

An internship at an Amoco chemical plant affirmed her decision to switch her major from chemistry to chemical engineering. When the company recruited her for another internship in the offshore business unit in New Orleans, she responded, “I don’t know anything about oil and gas, so sign me up!”

BP acquired Amoco in 1998, so Tanner has effectively worked for the same company for her entire career to date.

One of Tanner’s favorite positions was the year she spent as an operations engineer on a tension-leg platform.“I’m a hands-on person, and the experience really helped me understand how an offshore facility runs and learn how to communicate with the operators,” she says.

These days, Tanner spends most of her time on dry land in Houston, Texas, as the area team lead for Thunder Horse, BP’s largest facility (the size of three football fields) in the Gulf of Mexico. She is responsible for integrating drilling and completions, operations, and major project activities to inform business strategy and deliver value.

She says she prepared herself to take on team leader roles by volunteering to accept duties, such as allocations, that weren’t part of her job descriptions. “Always deliver more than your defined responsibilities. Stretching yourself can open up opportunities you never knew you were seeking.”

This is the type of career advice she offers to undergraduate engineers as BP’s Georgia Tech Campus Champion for job recruitment.
