Hari Rajaram, a beloved former faculty member in ����ֱ�� Boulder’s Department of Civil, Environmental and Architectural Engineering (CEAE), died unexpectedly on July 4 at his home in Baltimore. He was 59 years old.

Rajaram was globally recognized as a prominent figure in the field of environmental and Earth systems, known for his innovative use of mathematical models to understand and predict complex environmental phenomena. He was also a world-renowned expert in hydrology. 

In the department, he was affectionately called the “historian” for his phenomenal memory and revered for his methodical, well-organized teaching likened to a “precisely orchestrated symphony.” He was celebrated not just as a researcher, but also as an exceptional teacher, mentor, friend and role model. 

“Hari was that rare individual who combined strong intellect with humility and warmth,” said CEAE Professor Rajagopalan Balaji. “He had an attitude of selfless service, remained even tempered and empathetic and was an all-around wonderful human being.” 

Balaji shared that he frequently met with Rajaram during his tenure as department chair (2014-2022), “to seek his thoughtful counsel.” 

“Hari consistently advocated for and championed quality over quantity, providing an important voice,” he said.

Professor Emerita JoAnn Silverstein, who worked with Rajaram for 20 years, highlighted his impact during her eight years as department chair (2002 – 2010) when Rajaram served as the associate chair.

"Hari led numerous challenging tasks in service of the department, and I can’t recall any contentious issue that he could not resolve with his empathy, insight and sense of humor," she said. "That Hari embodied all the best facets of academic life was a source of inspiration to me and countless others."

CEAE Professor Roseanna Neupauer, who first met Rajaram when they were graduate students at MIT, echoed Silverstein's and Balaji’s sentiments.

“Hari had absolutely no ego and possessed a strong desire to uplift his community and every individual. With his clarity of mind to see the big picture, he approached contentious issues with a calm demeanor, grace and diplomacy, offering well-reasoned solutions that everyone could agree on. He was an outstanding teacher, patient and encouraging with all his students.” 

Balaji said Rajaram was the search committee chair who recruited him, and later Neupauer. 

“He is the reason we ended up at ����ֱ��,” Balaji said. 

A distinguished career

At ����ֱ�� Boulder, Rajaram was hired as an assistant professor in 1993 and rose to the rank as a professor of civil engineering in 2004, also serving as the department’s associate chair from 2006-2008. He received numerous teaching awards, including being named a President’s Teaching Scholar —the highest teaching honor in the ����ֱ�� system. He won nearly every award in the CEAE department from research to outstanding teaching. 

Also while at ����ֱ�� Boulder, Rajaram received a National Science Foundation CAREER Award (1998), collaborated with many CEAE faculty on various projects and served as the editor of the premier journal “Water Resources Research'' from 2013-2017.

In 2018, Rajaram moved to the Johns Hopkins Department of Environmental Health and Engineering and had served as deputy chair since that time. He was the editor-in-chief of “Geophysical Research Letters” from 2019 until his passing, and he was recently elected as Fellow of the American Geophysical Union.

Rajaram began his academic journey at the Indian Institute of Technology, in Madras, where he earned a Bachelor of Technology. He later pursued his MS at the University of Iowa. In 1991, he obtained his PhD in civil engineering from the Massachusetts Institute of Technology.  Following his doctoral studies, he completed a postdoctoral fellowship at Princeton University in the Department of Civil Engineering and Operations Research.

Neupauer shared a story from their time together as graduate students at MIT.

“����ֱ�� 10 years ago, a group of ����ֱ�� Boulder graduate students taking classes from both Hari and me discovered that when Hari and I were graduate students at MIT, we were finalists in an Irish jig competition at our lab's St. Patrick's Day party. When they asked Hari about the competition, he claimed he couldn't remember who won,” Neupauer said.

“Of course, this meant that Hari had won—because he never forgot anything and wouldn't want to brag,” she said.

Balaji also called Rajaram’s memory “phenomenal.”

“In almost all the conversations he brought a relevant historical perspective,” he said. “Even in technical discussions he would quote classic papers to offer richer insights. This was uniquely and quintessentially Hari.

"I will miss him.”
