Remembering Dr. Thomas Meixner

The University of Arizona community mourns the loss of hydrology and atmospheric sciences department head and professor Thomas Meixner, who worked to educate the next generation of water researchers and make our world's most precious resource safer for all.

Meixner is remembered as an incredible son, brother, husband, father, uncle, colleague and friend, and as an optimistic, selfless and a passionate teacher. He is survived by his wife, Kathleen Cotter Meixner, and sons Sean and Brendan.

Meixner grew up in Maryland playing in streams and digging in the garden. As an adult, he carried that same passion for water and the environment throughout his research.

"He was passionate about hydrology, and one of the last acts he performed on this Earth was to teach a class. He described his work as 'making the world better through biogeochemistry,' but to us, he was trying to save the world's most precious resource," his family wrote in a statement. "He recently retweeted the following quote: 'Hope is not optimism, which expects things to turn out well, but something rooted in the conviction that there is good worth working for.' Tom certainly lived this. He will be forever loved and missed by so many who knew him."

Meixner studied water in arid and semi-arid regions, with a focus on the American Southwest, which eventually became his home. His research interests included understanding how water influences the biology and geology of landscapes as well as where rivers source their water, urban hydrology in desert cities and the effect of climate change on groundwater recharge. His work spanned environments as diverse as desert scrub and Alpine ecosystems from scales small to large.

"Tom was a wonderful person, whose larger-than-life approach to being and doing inspired those around him and elevated the community. The world is different without him," said Carmala Garzione, dean of the College of Science. "As a cancer survivor, Tom shared with me that he chose to live life to the fullest and focus on things that are valuable to him and beneficial to the people around him. In the face of challenges, he always provided a positive and forward-moving approach."

Meixner earned his bachelor's degree in history of science, as well as soil and water conservation from the University of Maryland, College Park in 1992. He then came to UArizona, where he earned his doctoral degree in hydrology and water resources in 1999, with work focused on Alpine biogeochemistry.

He worked as an assistant professor in environmental sciences at the University of California, Riverside until 2004, before returning to UArizona as an assistant professor. He gained full professorship in 2015 and became department head in 2019.

"Dr. Meixner, an international force in his field of hydrology and atmospheric sciences and a kind and warm man, had a tremendous impact on his department and the students he mentored," University of Arizona President Robert C. Robbins wrote in a message to campus Thursday.

Michael Worobey, who heads the UArizona Department of Ecology and Evolutionary Biology, remembered Meixner as "one of a kind, incredibly smart, who always seemed to put his intelligence to work making the university community better and lifting up those around him."

Meixner was known to make weather forecasts, Worobey said, recalling a recent interaction that showed how much the late professor cared for those around him.

"The last time I saw him was at a recent College of Science reception," Worobey said. "Right at the end, a surprise storm hit, unleashing a respectable monsoon rain dump. Tom apologized, so sincerely, that he hadn't had time to generate a forecast that day that could have helped people plan around the storm. That was Tom in a nutshell – caring about those around him to a ludicrous, lovely, lovable degree, to the extent that he took personal responsibility for the weather. His loss is immeasurable."

This fund was established to honor his legacy, and the family will direct it to a University of Arizona cause meaningful to them.
