Mark Staskauskas Obituary

Published by Legacy Remembers on Mar. 16, 2026.
Mark Staskauskas UPPER Mark Staskauskas, 68, passed away on March 14 in Clear Lake, TX. Most recently residing in Galveston, TX, he was the husband of Susan Califa. Mark was born in Waterbury, CT, the son of Albert and Patricia (Bergin) Staskauskas. He was a graduate of Wolcott High School and held degrees in Computer Science from Columbia University (BS), UCLA (MS), and the University of Texas (PhD).

Mark worked in the telecom industry as a research scientist, engineer, and manager at Bell Laboratories in Naperville, IL, and at Qualcomm in San Diego, CA, until his retirement in 2015. His work involved frequent international travel to present his research at conferences and to represent Qualcomm in standards bodies. His wife Susan shared his love of travel, often accompanying him on these trips; they enjoyed many other memorable vacations worldwide and road trips together.

Mark was happiest when learning about things he was curious about. He was a lifelong music fan, and his love of Brazilian music inspired him to learn to speak Portuguese. Mark took great pleasure in good food and drink, and he maintained a regular exercise regimen to help burn off the calories. He enjoyed long walks and hikes, usually doing some birding along the way. Mark also had a passion for family history research. He completed detailed genealogies of his Lithuanian, Italian, and Irish ancestries and enjoyed helping others to build their family trees. A highlight of his genealogy research was finding and reconnecting with his relatives in Lithuania, whom he visited in 2009. During retirement he enjoyed researching and teaching adult learning classes in AI and Quantum Computing. His friends describe Mark as kind, caring, and a generous soul who treasured his friends and maintained lifelong friendships (eg, his "Math Heads" Club from High School is still a very close, supportive group of friends).

In addition to his wife of 32 years, he is survived by his sisters Susan Jones (Peter) and Barbara Marano (Cliff). If donations are desired, Mark was an an avid supporter of Galveston Island Nature Tourism Council, and an active member of Houston Area Parkinson's Society. While no formal services are planned, raising a bourbon-old-fashioned (or any beverage) with friends and family, or hiking/enjoying nature, would honor him.

Mark loved life and loved his friends and family. I am so thankful to have known Mark. He was kind, loving and brilliant. He was such a good friend to my husband and myself. He worked so hard and lived every minute like it was his last loving people and loving life. He had so much life to live and was taken far too soon. He loved Susan and would never have wanted her to see him suffer. I loved following them on all their fun travel and adventures. Mark was one of a kind and we miss him dearly.

I'll pack a bourbon flask and raise a toast on my next birding excursion - recalling good times watching Galveston birds with you Mark.

Mark was always willing to help people wherever he could, whether it be family history searches, explaining/teaching technical topics in ways people could understand, or just being present as a kind and genuine friend, never critical or judgmental, but always reassuring. His commitment to a daily exercise regimen to battle his illness, was a testament to his inner strength. A true gem in this world who will be missed by all who knew him.
