Dr Gillian Tully stepped down as Forensic Science Regulator on 16 February, after more than six years in the role.
The interim regulator has been named as Rupert Shute, Home Office Deputy Chief Scientific Adviser.
The Home Office reports that the recruitment competition for her replacement is currently ongoing and will be completed as soon as possible.
The Forensic Science Regulator ensures that the provision of forensic science services across the criminal justice system is subject to an appropriate regime of scientific quality standards.
Dr Tully took up the role in November 2014, and has worked in forensic science for over 25 years, specialising in DNA, innovation, validation and enhancement of quality standards.
She was honoured with a CBE for her services to forensic science in October last year, alongside her colleague Dr Jeff Adams who received an OBE.
