She will replace Nikki Holland at Merseyside who has joined the National Crime Agency as Director of Investigations.
Since 2014, Serena has been with Cheshire Constabulary where she is currently Head of Public Protection and Strategic lead for Early Help.
Serena previously worked at Greater Manchester Police, where she joined in 1993 as a Police Constable, working in local policing and partnerships up to the rank of Inspector.
She said: “It has been an absolute privilege to work at Cheshire Constabulary for the past three years.
“It’s an extremely helpful and welcoming organisation that really cares about the community it serves.
“I’m incredibly proud to have been the Head of Public Protection for 18-months and I’ve been impressed with the passion and commitment of the staff working in a challenging area of business.
“One of the many highlights came last year when the Constabulary was one of only 13 in the country to be rated as ‘good’ in the HMIC vulnerability inspection.”
Speaking about her now role Serena added: “I am absolutely delighted to have been appointed Assistant Chief Constable at Merseyside Police.
“Over the past few weeks I have spent time getting to know the force, its staff and its partners and I have been overwhelmed by the pride in the organisation and indeed the work being done across the partnership."
Cheshire Chief Constable Simon Byrne said: “Since joining the Force in 2014 Serena has made a huge contribution, particularly through her innovative work in public protection.
“We will be sad to see her go but are delighted for her that she has landed this fantastic new role at Merseyside Police. Her vast knowledge and experience will be a huge asset to Merseyside.
“It has been a pleasure working with Serena and everyone at the force wishes her all the very best for the future.”
