Aofei’s leadership, innovation, and commitment to excellence were critical to the successful delivery of this landmark FAA modernization effort. His contributions exemplify HMMH’s dedication to technical excellence, collaboration, and delivering outstanding results for our clients.
Please join us in congratulating Dayna, Erin, and Aofei!
Julia Nagy | Senior Managing Consultant, Aviation Environmental & SustainabilityHMMH partnered with Dane County Regional Airport to support the FAA resubmittal of the Airport’s Noise Compatibility Program (NCP). Julia played a key leadership role throughout the effort, serving as the primary author of the project scope and fee estimate while ensuring alignment with the Airport’s goals and FAA requirements. As the primary point of coordination, she worked closely with the Airport Director, project team, and stakeholders to guide the project to completion.
Julia managed a comprehensive public involvement program that included Technical Advisory Committee meetings, Airport Noise Abatement Subcommittee meetings, multiple public meetings, and a final public hearing. She also led the preparation of responses to public comments, helping ensure a transparent process that addressed community input and regulatory requirements. Through her leadership, organization, and commitment to client service, Julia helped deliver a successful NCP submittal that advanced the Airport’s objectives.

Justin developed a unique cloud-based process for computing noise metrics from flight track data using AEDT, applied across 74 airports and thousands of receptors for multiple case years. By leveraging AWS-based parallel computing, his approach produces results many times faster than traditional AEDT methods. This innovative process has the potential to transform AEDT modeling for clients by reducing or eliminating the need for bundled flight track creation and significantly expediting model runs.
In addition to his work on AEDT, Justin utilized his advanced Python programming expertise to calculate rolling cumulative metrics, including daily DNL values over a four-year period from 2020 to 2023. These timely and comprehensive analyses have been instrumental to the project’s Principal Investigator, Dr. Mathias Basner of the University of Pennsylvania, in correlating noise exposure with sleep disturbance toward the development of a new FAA Noise Policy dose-response relationship.

Aofei Li exemplifies HMMH’s commitment to innovation and excellence in aviation environmental and sustainability projects. As part of the Toronto Pearson International Airport Vision Plan, Aofei took on a critical role in advancing noise modeling efforts to meet project requirements and client needs. Aofei mastered the software NEFCalc, Transport Canada’s official noise model, ensuring successful application in the analysis. He led the modeling team in adapting and converting inputs for compatibility with NEFCalc, developed a rigorous quality assurance and control (QA/QC) framework, and implemented a streamlined process to validate data and ensure traceability. These efforts not only ensured accurate results but also supported the project’s tight schedule, meeting deadlines with precision.
Aofei’s innovative QA/QC tool has had lasting benefits beyond this project, improving efficiency, supporting comprehensive documentation, and providing a replicable process for future projects at HMMH. His leadership and dedication have been instrumental in delivering exceptional outcomes for our clients and advancing HMMH’s capabilities in noise modeling and analysis.

Kate Larson was recognized for her outstanding work on the 2022 L.G. Hanscom Environmental Status and Planning Report. Her exemplary performance and efforts have significantly contributed to the project’s success. This project required a local project manager to oversee its execution, encompassing a comprehensive environmental and planning overview of the airport, akin to a full Environmental Assessment, with noise and air quality being just part of the scope. To support areas beyond our expertise, we collaborated with two subcontractors.
Kate managed the project with exceptional organization, conducting effective team meetings and maintaining momentum. Despite lacking support from staff experienced with the previous project, Kate excelled in handling many project elements outside her prior experience. Her efforts were further complicated by the simultaneous development of a controversial hangar project, requiring her to coordinate public outreach and project scheduling with the client to avoid potential issues.
Without Kate’s leadership, our longstanding reputation with the client could have been at risk. The project’s total budget was exceeded, and Kate’s management skills have proven she can handle projects of this magnitude in the future. The client’s staff are extremely satisfied with the project’s outcome, and Kate is highly deserving of this award.

Tara’s work on the I-495 North Extensions Express Lanes Design-Build Project (495 NEXT) exemplifies HMMH’s commitment to quality, technical excellence and innovative problem-solving.
The 495 NEXT project is a public-private partnership between the Commonwealth of Virginia and Transurban that involves extending the 495 Express Lanes north by two-and-a-half miles from the Dulles Corridor to the George Washington Memorial Parkway interchanges near the American Legion Bridge. HMMH is teamed with Rinker Design Associates to deliver this design-build project with an approximate cost of $500 million.
Serving as HMMH’s project manager and overseeing our modeling team, Tara delivered the final noise barrier design technical analysis on time, exceeding client and agency (VDOT) expectations, and kept the project within budget. This complex project included analysis of replacing existing noise barriers that would be displaced by, or rendered less effective, by the project or rendered less effective, reflections of traffic noise off barriers, multiple design changes with tight turnaround times, and effectively managed concerns from the surrounding community over noise from the project.
Paul Krusell | Consultant, Federal ProgramsPaul exemplified an inspiring commitment to quality and excellence, which not only exceeded client expectations but has also set a remarkable standard for all at HMMH.
As the modeler for the PHL Master Plan Update, Paul was responsible for updating and running the project’s AEDT models. The PHL Master Plan Update modeling was based on a set of legacy models with limited documentation and information available for reference. As the models were updated and tested, several issues were found and needed to be corrected. Throughout the project, Paul tirelessly investigated the issues, tracked down error sources, and updated the models and data to understand and rectify the errors. He meticulously reviewed the modeled contours for errors and investigated possible reasons for contour differences. Paul also provided clear explanations of the errors and changes made to the models so that the client could understand the changes and have confidence in our analysis. These efforts and dedication are not unusual for Paul, but they are a shining example of what HMMH strives for in all our analyses.
