“We are a complete mobile research unit,” says pollution researcher Steve Allen about his long-term collaboration with his wife, Deonie Allen. Working together with a romantic partner has clear benefits: you share the same passion for science and understand each other’s challenges and stresses. At the same time, finding two jobs in the same location can be difficult, particularly when you share a speciality. “It’s true we wake up talking science and go to sleep talking science,” says Steve. “But we wouldn’t have it any other way.”
