Marran, David F.

David Francis Marran, 56, of Durham, devoted husband of Wendy (Genga) Marran, passed away on Friday, February 23, 2024 at Yale New Haven Hospital surrounded by his loving family. He was born in Greenwich, CT, son of the late John D. and Lorraine (Burton) Marran. Dave attended Bates College in Lewiston, Maine, where he met his future wife, Wendy. They spent nearly 40 wonderful years together and Maine always held a special place in their hearts. He earned his PH.D. in Mechanical Engineering from Yale University. For the last 15 years, Dave was employed as the Director of Engineering for Thermofisher Scientific in Guilford, CT. He contributed to all aspects of the company's genetic sequencers, from inception and development to manufacturing and product launch. He loved his job and was a creative and caring mentor to all. Dave was a humble and grateful man. He enjoyed spending time with his family, fishing, kayaking, hiking, and riding his Peloton. He had a quick wit and an even quicker smile. His love of family and friends and his endless optimism sustained him throughout his life, and especially in the last three years as he battled Glioblastoma. His courage and strength continue to inspire all who knew him. His family would like to thank his teams at Smilow Cancer Hospital, Dana Farber Cancer Institute, and especially Gaylord Rehabilitation Hospital. Dave is survived by his wife, Wendy; cherished daughters, Sarah, Olivia, and Abigail Marran; brothers, Roger (Nadine) Marran, Kenneth (Lynn) Marran; sister, Margaret Marran; as well as many nieces and nephews.
