SAD NEWS
Many of you will know Pam Sydelko, who was a member of the ISSS and graduated with her PhD from our Centre for Systems Studies at the University of Hull in July 2023.
I’m sad to report that she passed away recently, surrounded by her family, following a three-month illness.
I am taking the liberty of sharing links to two open access (free to download) papers in the European Journal of Operational Research that Pam wrote out of her PhD, which are a legacy of her contribution. One of them has a 2024 date, so will be a posthumous publication, and I’m glad that Pam saw it accepted while she was still with us. Both papers are picking up citations at a healthy rate, so I am optimistic that Pam’s influence will continue with us for a good while.
