2024 College of Science and Mathematics Outstanding Alumnus

Born in 1970 to Paul and Lois, Neil Thiesing has spent his life in the Dayton area. With his brother Kyle, he was raised in Miami County and graduated from Newton High School in 1988.

It was at Wright State where Thiesing developed a lifelong interest in chemistry, leading to a bachelor’s degree in 1992 and a master’s degree in organic chemistry in 1995. In 1991, while still a student, he joined Daychem Laboratories, a Dayton company founded by Wright State alumnus Rakesh Gupta and his professor, Frank Harris.

Working his way through college, Thiesing took on various jobs at Daychem: R&D technician, production operator and technical manager, learning as much as he could not only about synthetic chemistry and international business but also about the value of hard work and relationships.

He later became a partner at Daychem and helped steer it into a hugely successful business acquired by Heraeus, a German technology leader, in 2012. Thiesing is currently Heraeus’ global head of product portfolio for semiconductor chemicals. While based in Vandalia, his responsibilities span many countries, and under his leadership, the company has become a key player in the global semiconductor industry.

He also sits on various boards of directors, such as the Miami County Educational Service Center, where he has served for 14 years, and the Miami County Foundation. He is also a part owner of two manufacturing businesses in the Dayton area, serving as an adviser.

Beyond his career, Thiesing considers having many loving family members and friends to be the true measure of success. This includes his wife of 25 years, Lori, and his wonderful children, Drew, and the twins, Reese and Brock, who were all raised in Miami County. In fact, Reese currently attends Wright State.

Faith is a pillar in Neil’s life, and he and his family proudly serve at the Cornerstone Baptist Church in Troy.

Acknowledging that his passion for chemistry was first catalyzed at Wright State, Thiesing hopes to continue partnering with Wright State’s College of Science and Mathematics to mentor others who may follow a similar path.

“It’s rewarding to give back locally even while working internationally,” he said.

He is humbled and thanked Wright State for honoring him with the 2024 College of Science and Mathematics Outstanding Alumni Award, which, he said, was made possible by his faith and the support of his family, friends, colleagues and teachers throughout the years.
