Cambridge Recommendation Letter Example: Air traffic systems analyst to transport regulation (Score 92)

I am an Associate Professor of Law and Regulation at , where I supervise postgraduate dissertations at the intersection of regulatory theory and infrastructure governance. I write in support of the applicant's candidacy for the MPhil in Public Policy at Cambridge, having supervised their dissertation over approximately nine months during the [academic year]. That period gave me sustained, close-range observation of how they think, how they handle criticism, and how they develop an argument under pressure. The applicant came to me with a background in aerospace engineering and a working focus on air traffic optimisation. That combination is less unusual than it sounds — aviation systems are among the more heavily regulated technical domains, and students who arrive with genuine quantitative fluency sometimes make sharper regulatory analysts than those trained exclusively in law or politics. What I wanted to see was whether the applicant could move from engineering logic to regulatory reasoning: not just modelling a system, but asking who governs it, under what authority, and with what distributional consequences. The dissertation examined regulatory frameworks governing urban airspace and surface transport integration — a topic that sits squarely at the boundary of technical systems analysis and public policy. Early drafts were competent on the technical side and thinner on the normative. In one supervision session around the third month, I pushed back on a section that described current air traffic management protocols in considerable detail but treated the regulatory structure as essentially given. I asked the applicant to explain why the existing allocation of oversight authority made sense from a public interest standpoint, and what a challenger might say against it. The response in the room was hesitant — this was clearly less familiar ground — but the revised chapter submitted two weeks later showed genuine engagement with the accountability literature I had suggested. The applicant had not simply grafted citations onto the original argument; they had restructured the section's logic. That kind of revision is not universal among dissertation students, and I noted it. A second scene is worth describing. Midway through the project, the applicant presented a memo-style policy analysis to a small internal seminar — a format I use to test whether students can translate technical findings for a non-specialist audience. The memo concerned congestion pricing mechanisms applied to low-altitude urban airspace, drawing on the applicant's earlier air and traffic analysis work. The technical framing was clear and well-evidenced. The challenge came during questions, when a colleague asked about equity implications for operators who could not absorb variable access costs. The applicant's initial answer was largely efficiency-focused. After a brief pause, they acknowledged the gap directly and offered a provisional framing rather than defending the original position. That willingness to revise in real time, rather than retreat into technical authority, suggested a kind of intellectual honesty I value in policy researchers. I should be candid about one area of development. The applicant's instinct, when facing a contested normative question, is still to reach for quantitative evidence first. That is not a weakness in itself — rigorous policy analysis needs it — but in a programme like the Cambridge MPhil, where qualitative reasoning, institutional analysis, and political economy sit alongside methods training, the applicant will need to be deliberate about engaging those registers with equal confidence. I raised this in our final supervision meeting. The applicant received it well and articulated a clear sense of what they wanted to work on. I mention it not as a disqualifying concern but because I think Cambridge's programme structure is well-suited to address it, and the applicant is self-aware enough to use that structure productively. In terms of independent working, the applicant managed a complex, multi-strand project across a long timeline without significant supervisory intervention on logistics. Drafts arrived on schedule. When they did not, I received advance notice and a revised plan. That kind of professional reliability is not glamorous, but it matters for research-intensive postgraduate work. I supervise roughly [number] dissertations per year across engineering-law and regulatory policy tracks. The applicant sits in the stronger portion of that group — not because the work was flawless, but because the trajectory was consistently upward and the engagement with difficult feedback was genuine. I would be comfortable supervising this person again at a more advanced level, and I think the MPhil in Public Policy at Cambridge represents a well-matched next step for the kind of analytical development I have observed.
