Since graduate studies, my long term research program has been on the ecology of Sphagnum species in peatlands, first as impacted by acid rain (nitrogen deposition) and lately understanding their distribution and regeneration niche at early successional stages after disturbance. This will remain one main theme of my research programme but other groups of bryophytes such as brown mosses dominating fens and boreal pioneer upland bryophytes will also be studied. The general purpose of the research program will be to provide essential knowledge about what factors determine the success of establishment of mosses colonizing disturbed soils in peatlands (both for bogs and fens) or boreal and sub-arctic uplands. A focus of study will be on facilitation (how some plants benefit from growing in close association with neighbours) and how this plant-plant interaction relationship can contribute to theoritical plant ecology and improve our predictive ability of successional pathways.

自研究生学习以来，我的长期研究计划一直是泥炭地泥炭藓物种的生态学，首先受到酸雨（氮沉降）的影响，最近了解它们在干扰后的早期演替阶段的分布和再生生态位。这将仍然是我的研究计划的一个主要主题，但其他群体的branchites，如棕色苔藓占主导地位的沼泽和北方先锋高地branchites也将进行研究。该研究计划的总体目的是提供有关哪些因素决定了苔藓在泥炭地（沼泽和沼泽）或北方和亚北极高地的扰动土壤中成功定居的基本知识。研究的重点将是促进（一些植物如何受益于与邻居的密切联系），以及这种植物与植物的相互作用关系如何有助于理论植物生态学和提高我们的预测能力的演替途径。
