田林瑋教授從事環境流行病學研究，尤其專注於空氣污染與健康的關係。他曾在女性肺癌死亡率居中國首位的宣威市，就空內空氣污染和肺癌進行現場環境研究及實驗室研究工作。他針對數百個農村的用煤模式和肺癌死亡率進行空間分析後， 提出了以下假設：煤煙中的結晶二氧化硅（石英）是導致肺癌在宣威農村蔓延的重要風險因素 。最近，他致力於量化石英及其他存於煤煙的致癌物質，以及探討這些物質與癌症有否劑量反應關係 。如證實這種關係的確存在，他會提出禁止在中國的住宅區使用某些有毒煤炭。此外，他將鑑定和分離存於煤煙的致癌物質，推薦用作實驗室致癌機理研究的標準物質之一 。

香港城市發展急速，環境特徵獨特，是另一個空氣污染和健康關係的研究現場。香港人口和交通密度甚高，高廈林立，而且環境測量和醫療衛生相關數據豐富，又有各種空氣污染控制措拖，值得環境流行病學深入研究。田教授已利用覆蓋全港的公開數據進行探索性分析，並就本港的污染物和污染源可引致的健康危害提出假設。在更多的個人暴露和生物標記物數據的基礎上，他將會展開分析性研究， 進一步驗證這些假設，推斷可能的因果關係，並建議以健康風險為指向的空氣質量控制政策。
