In 2013, Baker Hughes teamed up with the School of Aerospace and Mechanical Engineering and the Mewbourne School of Petroleum and Geological Engineering at the University of Oklahoma to start a partnership with its students and Baker Hughes known as the 21st Century Co-op. The BHI 21st Century Co-op is a five year accelerated Bachelor of Science/Master of Science degree program in mechanical engineering or petroleum engineering. In addition to the required courses for both degrees, the BHI 21st Century Co-op curriculum includes customized courses offered by faculty and BHI engineers during summer internships, a senior capstone course, graduate cross-disciplinary courses and graduate theses all relevant to Baker Hughes and its initiatives.
Through the BHI 21st Century Co-op, sophomores studying mechanical and/or petroleum engineering are invited to apply for the program. Students must submit an application including a resume, transcripts and an essay. Baker Hughes personnel interview a short list of candidates, and in consultation with the OU mentors, invite sophomores to become BHI Scholars. Baker Hughes and the OU mentors seek students who want to further their education with a master’s degree and those who are very career-driven with high professional goals.
“Integrity, teamwork, performance, learning and courage are the core values of Baker Hughes. These traits are what it takes to be a BHI Scholar,” said Jerry Varughese, mechanical engineering junior and BHI Scholar. “Our team seeks individuals who are willing to go above and beyond expectations. Our team looks for individuals who are willing to work hard but also always ready to learn.”
The aim of the program over the next three years is to enable BHI Scholars to work as a team on different aspects of a challenge problem identified by the BHI mentor. This year 11 BHI Scholars worked on the challenge problem. The mechanical engineering BHI Scholars are Wiley Abbott, Miles Burnett, Eric Douglas, Brandon McCabe, Chris Sanders and Jerry Varughese. The petroleum engineering BHI Scholars are Bryan Bodie, Pamela Duarte, Dallas Milligan, Dana Saeed and Alex Smith.
“The mix of petroleum and mechanical engineers brings a unique dynamic that allows us to constantly keep learning different perspectives,” said Eric Douglas, mechanical engineering senior and BHI Scholar. “The best part of this experience is the ability to work as a team.”
Something different with this program is its focus on interdisciplinary and collaborative learning. “Taking both petroleum and mechanical engineering classes is beneficial to creating a diverse educational background that will brand the BHI Scholars as a more valuable asset in the workplace, as well as well-rounded engineers,” said Dallas Milligan, petroleum engineering sophomore and BHI Scholar. “Having a perspective from both disciplines gives the BHI Scholars a chance to see problems from a different view, which can make all the difference in creating a unique solution.”
On April 26, 2015, the Baker Hughes Scholars presented their solutions to the challenge problem to BHI mentor and engineer Larry Watkins. The challenge presented to the BHI Scholars focused on an overview of unconventional hydrocarbon resources, primarily shale plays and to review and identify the go forward challenges facing development of shale.
On April 27, 2015, Rustom Mody, Vice President/Chief Engineer for Baker Hughes Enterprise Technology and the principal sponsor of the BHI 21st Century Co-op Program, presented a check for $160,000 in support of the program.
“The commitment from both Baker Hughes and the faculty sponsors to the program is encouraging. The faith they have in the scholars as they develop us into future contributors to the oil and gas industry definitely drives us to do our best,” said Alex Smith, junior in petroleum engineering and BHI Scholar. “Having this support system to challenge and force us out of our academic comfort zone has been my favorite part of this experience.”
Faculty sponsors of the BHI 21st Century Co-op are Farrokh Mistree, AME; Maysam Pournik, PGE; Chandra Rai, PGE; and Zahed Siddique, AME. For additional information, please contact Farrokh Mistree, firstname.lastname@example.org.
Dr. Diana Bairaktarova, Assistant Professor of Engineering Practice, was recently featured on Current Conversations with Robert Con Davis-Undiano. Dr. Bairaktarova discusses her research and focuses on design thinking and the human experience.
This one-on-one lively forum features people who are making a difference in the world—scientists, educators, humanists, writers, and artists. The goal is to focus on people who function as “bridge builders,” or people in the culture who are making important connections between areas of knowledge.Each week the show finds relevant connections between people and areas of knowledge that really matter and gives its viewers a close-up perspective on important developments changing the world around them.
“I hope people will watch the show and be delighted at the research that’s being done at the University of Oklahoma,” Davis-Undiano said. “It’s a chance to meet some accomplished and brilliant people.”

Dr. Jivtesh Garg, AME Assistant Professor, and fellow research members recently developed a model that explains how heat flows between objects separated by gaps of less than a nanometer. The team has developed an atomistic framework that successfully predicts the magnitude of heat transfer across all gaps ranging from finite sizes all the way to perfect contact. The work overcomes the shortcomings of previous continuum based models which predict a diverging behavior at short length scales.
Through this model the team demonstrated that at gaps of few atomic layers, lattice vibrations (phonons) can tunnel through (normally associated with conduction heat transfer) in addition to heat transfer through evanescent electromagnetic modes (near-field radiation) blurring the separation between conduction and radiation at short length scales. By using microscopic Maxwell’s equations energy transfer was directly expressed in terms of short-range forces and long-range Coulomb forces between atoms on either side of a gap avoiding the need for use of any bulk macroscopic properties such as the dielectric constant. Such a purely atomistic framework of describing heat transfer can also benefit from ab-initio calculations that provide short-range interactions through solution of the underlying quantum-mechanical problem.
The work has implications for practical applications where heat transfer at small gaps is becoming increasingly relevant such as heat-assisted magnetic recording and nano-structured aerogel materials. By providing an accurate atomistic description the work also paves way for development of non-local dielectric constant which can be integrated into continuum models allowing an easier prediction of thermal transport at these small gaps.
The research team is made up of Vazrik Chiloyan, Massachusetts Institute of Technology; Keivan Esfarjani, Rutgers University; Gang Chen, Massachusetts Institute of Technology; and Jivtesh Garg.

Abstract: This seminar presented the use of quantitative atomic force microscopy based indentation to characterize the mechanical properties of a carbon fiber–epoxy matrix interphase at highly localized length scales. Atomic force microscopy is a valuable tool for qualitative characterizations of material surfaces. Nonetheless, its application to quantitative measurements is hampered by various technical issues. Accordingly, the talk will discuss how issues such as spring calibration, tip geometry, surface roughness and substrate effects were taken into account to obtain accurate quantitative mechanical proper ties of interphase region.
Lastly, the seminar discussed the use of surrogate modeling to characterize non-linear viscoelastic materials based on inverse analysis of indentation data. In this form, the technique can be extended to study mechanical properties complex biological structures such as the ear-drum (or tympanic membrane) or the heart wall.
