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，我的长期研究项目是泥炭地泥炭炭疽菌物种的生态，首先是受酸雨(氮沉积)的影响，最近是了解它们在受干扰后的早期演替阶段的分布和更新生态位。这将仍然是我研究计划的一个主要主题，但其他苔藓类植物，如占沼泽的棕色苔藓和北方先锋旱地苔藓植物也将被研究。该研究计划的总体目的将是提供基本的知识，即什么因素决定了在泥炭地(沼泽和沼泽)或北方和亚北极高地的受干扰土壤上建立苔藓的成功。研究的重点将是促进(一些植物如何从与邻居密切相关的生长中受益)，以及这种植物-植物相互作用关系如何有助于理论上的植物生态学，并提高我们对演替路径的预测能力。
