Correspondence from Dr Lucien Heurter and Dr Simon Williams, re: STFC reprioritisation and PPAN early-career researcher pipeline, 16 June

From: Science, Innovation and Technology Committee

Summary

Early-career particle physics researchers challenge STFC funding reassurances, arguing the committee was misled about postdoctoral position protection. They present evidence of a 39% reduction in theoretical particle physics posts (41 to 25 FTEs) and survey data showing 74% of UK postdocs are considering leaving, with only 8% recommending UK PPAN careers post-January 2026 funding cuts.

Key findings

Lord Vallance and Sir Ian Chapman's April 2026 reassurances obscured actual reductions by comparing against a hypothetical 2025 grant round rather than grants actually in place; theoretical particle physics faces 39% postdoctoral FTE reduction (41 to 25) for 2025/26
Estimated 220–260 postdoctoral positions across PPAN community are at risk if cuts are not mitigated; 2026 recruitment cycle for theoretical particle physics already missed
Survey of 457 PPAN researchers shows only 8% would recommend UK PPAN career (vs. 74% pre-January 2026); 74% of current UK postdocs actively considering leaving; 89% report low/very low confidence in UK postdoctoral opportunities
79% of survey respondents felt less reassured by recent announcements; only 4% said they largely addressed concerns
Early-career researchers making permanent career decisions based on unreliability of UK pipeline; risk of losing trained cohort whose expertise cannot be recovered later

Notable line

“Only 8% of respondents would now recommend a career in UK PPAN, compared with 74% before the January 2026 funding announcements.”

Key Quotes

“A comparison with a hypothetical 2025 grant round therefore obscures the reduction in posts supported by the grants actually in place for 2025/26.”
— Dr Lucien Heurtier and Dr Simon Williams · explaining the discrepancy in STFC's reassurances about maintained postdoctoral positions

“… theoretical particle physics is facing a reduction from 41 postdoctoral FTEs to 25, a 39% reduction even before comparison with the uplifted level.”
— Dr Lucien Heurtier and Dr Simon Williams · concrete example of PPAN-wide funding cuts

“… early-career researchers are already making career decisions on the basis that the UK pipeline is no longer reliable.”
— Dr Lucien Heurtier and Dr Simon Williams · describing impact of funding cuts on researcher retention

“Without a genuine restoration plan based on the needs of the PPAN programme, rather than an already-reduced baseline, the UK risks losing a cohort of trained researchers whose expertise cannot simply be recovered later.”
— Dr Lucien Heurtier and Dr Simon Williams · final warning to committee about long-term consequences
