Roman is the next NASA flagship mission after JWST, at a cost of $4.3 billion. It will launch in late 2026 and will spend around 25% of its 5-year nominal mission on the Galactic Bulge Time Domain Survey (GBTDS). Transits in the Roman Exoplanet Survey (TRExS) is a NASA selected survey to search for transiting exoplanets within the GBTDS dataset. TRExS is expected to find 60000 to 200000 transiting exoplanets, increasing the number currently known by more than an order of magnitude. Kerins leads Working Group 2 (survey optimization and exoplanet demographics) for TRExS and this project will form a major contribution to the preparatory work of the group. The project will involve building a Galactic simulation of exoplanetary systems in order to assess the sensitivity of Roman exoplanet yield to demographic parameters including host separation, planet-host mass/size ratio, eccentricity and mutual inclination.

罗曼是JWST之后的下一个NASA旗舰使命，耗资43亿美元。它将于2026年底发射，并将其5年标称使命的25%用于银河系膨胀时域调查（GBTDS）。罗马系外行星巡天凌日（英语：Transit in the Roman Exoplanet Survey，缩写：TRExS）是美国宇航局的一个选定巡天，用于在GBTDS数据集中搜索凌日系外行星。TRExS预计将发现60000至200000颗凌日系外行星，使目前已知的数量增加一个数量级以上。Kerins领导TRExS的第2工作组（调查优化和系外行星人口统计），该项目将对该小组的筹备工作做出重大贡献。该项目将涉及建立一个系外行星系统的银河模拟系统，以评估罗马系外行星产量对人口参数的敏感性，这些参数包括宿主分离、行星-宿主质量/尺寸比、偏心率和相互倾斜度。
